Universal multimeter UT139C with a high resolution will be appreciated at development and everywhere, where you need to find out a situation in a given device accurately
Imagine a situation, when you need to check or set a voltage of 3.3V or 5V usual at digital electronics (AD converters reference,…). Or to measure the end of recharging of Li-ion/ Li-Pol batteries at 4.20V when it really matters on every miliVolt. In these cases, with usual multimeters you´ll face one cardinal fact – regarding that the most of them has a max. display reading of 1999, you´ll measure in hardly the first quarter of a range, thus with a significantly lower resolution. For example instead of desired 4.001 V (3 decimal positions), you´ll only see 4.00V. Naturally, we don´t always need such a high resolution but many times an improvement of resolution in one magnitude can provide us a worth information about a real situation in a measured circuit. In these situations it often doesn´t matter on the absolute accuracy that much, but right on a resolution, especially when comparing voltages in two points, increase/ decrease…
From this point of view is the novelty in our stock UT139C an excellent device providing besides a high resolution (5999) also another features worth to notice, for example: TRUE RMS measurement in a range of 45Hz-1kHz (to 400 Hz with VFC filter activated), measuring of high-capacity capacitors up to 99.9 mF (99 999 uF), measuring of duty cycle in a range of 0.1% – 99.9% and other. Not quite common is also measuring of uA and mA even in AC range. Function Rel is useful even at measuring of small capacitors, where it´s able to eliminate “offset” caused by a capacitance of testing leads.
A thermometer (K type) with arrange of -40 to 1000°C can also be useful at development. From some point of view it´s advantageous supplying by two AA cells, not by a classic 9V battery (AA cells have a better capacity/ price ratio).
UT139C is also able to serve as a non-contact AC voltage tester (NCV), indicating in 4 steps a proximity of >100VAC voltage. . Indication is by a red LED in the upper part of display, by a display (-,–,—,—-) and by a buzzer.
Further information will provide you the UT139C datasheet.

Calibrated differential pressure sensors will find usage in industry and also in every smart home.
Ventilation, air conditioning (HVAC), or any other applications, where a pressure or a flow of air (gas) is essential, can be precisely regulated only if we know a real pressure/ flow conditions. Monitoring of fans functionality, status of filters, …, even for this purpose are very suitable differential pressure sensors from Swiss company Sensirion with an excellent accuracy and long-term stability.
As SDP sensors are differential, they have 2 nozzles. The base of these sensors is a miniature heating element and two temperature sensors. Difference of pressures will cause a small air flow through a component and it will cause a temperature difference in these built-in sensors. Temperature difference is directly depending on the amount (weight) of air flowing through a sensor and it naturally depends just on a pressure difference. A great advantage against membrane pressure sensors is a long-term high accuracy even at measuring of small pressure and maintaining of accuracy of a “zero point”.
As an air specific weight depends on temperature, measurement based only on a temperature difference of two internal sensors wouldn´t be accurate. That´s why SDP sensors have a built-in temperature compensation and linearization, thus an output of a sensor is directly a value usable for further processing. Resolution of sensors is very high and is user selectable in a range of 9-16 bits. Resulting binary value read-out through I2C interface can be divided by a constant shown in a tab. 2.1 on page 3 of the SDP6xxv1.7 datasheet and we´ll get a resulting value in desired units (Pa, bar, inch).
Universal and price-attractive series is the SDP600 (6xx) series, in which we´ll find types optimized for measurement of pressure (SDP 600/610), mass flow (SDP601/611) and types with a minimal power consumption suitable even for battery-operated devices (SDP606/616). All these types are able to measure “bidirectionally” i.e. positive and even negative values. For applications, where we know, that a pressure difference will be always positive (flow by only one direction), it´s possible to use more price-affordable types SDP 500/510 (in fact even these types measure bidirectionally, but their accuracy is not guaranteed in this range). For the most of applications no additional compensation is necessary, only it can be necessary to multiply a resulting value by a constant for an altitude compensation shown in a table 5.4 on page 6 in the datasheet.
How can be this small sensor used to measure flow of a big amount of air?
Relatively simply. All that is necessary is to make a small orifice in a pipe and this way to create a “resistance” as described in the SDPxxx_Bypass_Configuration application note. In an electronics analogy the differential pressure measurement is similar to measurement of voltage on a resistor, which depends on a current flowing through a resistor. SDP sensors can be used even for measurement of a pressure difference in a given pipe against a surrounding environment, in such a way, that one nozzle of sensor will be left “unconnected”. Naturally, such a configuration can only be used if a small leakage of a measured “gas” (air) is acceptable.

Series of the Osram Duris S5 white LEDs brings an excellent version for an excellent price, while maintaining a long lifetime and a high CRI.
Series of the Osram Duris S5 white LEDs brings an excellent version for an excellent price, while maintaining a long lifetime and a high CRI. Some members of the family of mid-power LEDs Osram Duris were introduced to you a year ago in the article A light without an end with OSRAM Duris E3 and E5 LEDs. So far, these basic series were available:
- Duris E3 – white LEDs LED 3×1.4 mm with a max. current of 30 mA in a cost-effective plastic package. Suitable for general usage in lighting, mainly at construction of replacements of classic light sources (retrofits)
- Duris E5 – white LEDs 5.6×3 mm with a max. current of 180 mA in a cost-effective plastic package. Suitable for general usage in lighting, mainly at construction of replacements of classic light sources (retrofits)
Duris P5 – white LEDs 2.6×2.2 mm with a max current of 200mA in a resistant ceramic package. Handles high temperatures, extremely resistant to corrosion, long lifetime. Suitable for professional usage in lighting, mainly at construction of powerful light sources with a long lifetime.
The latest increase of the Duris family is the S5 series, which so to say merges the best of the E5 and P5 series. In other words Duris S5 represents a “golden middle way” between E5 and P5 and brings an excellent economical effectivity (low price), high light output and a very good lifetime. S5 is produced in a small epoxy-based package (3x3mm) with very good thermal properties. what enabled to increase power of this series.
Duris S5 also brings another valuable feature – high flexibility, because a pinout is the same as in several competition products and mainly
Notice the double voltage at the type PSLPS1, what indicates, that inside it contains 2 LEDs connected in series and at the same time it mains practically double power in comparison to type MS1. Features of particular types are best illustrated in an attached table. It´s also worth to notice the value „binning current“ and also columns „Typ. flux“ and „Typ. efficacy“, which display measured values at a given testing current. High efficacy up to 125lm/W at the type MS1 is reached at current of 65mA and serves mainly as a reference value for comparison with other LEDs from other producers, which are often tested just at such lower currents (even though in fact the type MS1 can handle up to 240 mA). In general it applies to all white LEDs, that they reach a higher efficacy at lower than maximum currents, mainly thanks to a lower chip temperature.
Into our standard stock offer we incorporated the most powerful type GW PSLPS1.EC in a warm white (3000K) and a cold white (5000K) version. Despite truly miniature dimensions, it is a considerably powerful LED with a max. power of >1W for a very affordable price. . Interesting and in praxis still more used is a possibility to use both types on a PCB (warm and cold white) and by means of a variable driving current we can change a resulting color temperature of a radiated light from warm to a cold white – according to a wish or a frame of mind of a user.
Further information will provide you the Duris S5 datasheet. It´s also a good news, that Osram promises to launch on the market a version with a min. 90 CRI.

This interesting spray from the Kontakt Chemie portfolio will serve in an office but also at the production of electronics and in many other segments.
Name “Label off” discloses a main purpose of usage of this spray. But that´s not all. Because Label Off is a mixture of solvents which particularly well dissolve sticky substances, it can be successfully used everywhere, where it´s necessary to remove residues after adhesive tapes or other hard-to-remove substances like tar and tree resin. Despite a considerable effect, the spray is considerate to many plastics, only can´t be used on polystyrene and polycarbonate. Label Off can be even used on a cardboard/ paper boxes.
Label Off acts very simply – all that is necessary is to spray a thin layer to a label or other place, which we want to clean and wait approx- 2 minutes. After this time it´s usually possible to peel-off a label without residues. Occasional residues can be removed by a repeated application of Label Off and wiping by a (paper) cloth.
Detailed information will provide you the Label Off datasheet.

New series of miniature embedded industrial computers of the credit card size manages HD videos, multimedia presentations and other demanding tasks in a real time.
i.MX53 is after i.MX25 and i.MX51 already the 3-rd member in the family of computers i.MX (SBC – Single Board Computer, COM – Computer On Module) from company Voipac. A big advantage of a common concept, i.e. usage of common operating systems is, that these computers are cross-compatible, thus all experience, programs and drivers, which you have for example from development of applications for i.MX25, are also usable for i.MX53.
OS Linux, Android and soon also Windows Embedded compact 7, USB 2.0 OTG/HOST, LCD 1600×1200 controller, ethernet and many other built-in peripherials make the i.MX53 a top choice for devices with small dimensions. A high-performance 1.2 GHz multimedia processor i.MX535 from Freescale provides a high performance at a low power consumption (passive cooling). i.MX53 is constructed on only 1mm thick 10-layer HDI board with microvias and provides a vast majority of peripherials expected from embedded systems. i.MX53 is able to boot not only from NAND Flash memory, but also from I2C EEPROM, SPI Flash and uSD card (all 3, including a uSD connector are on the board).
i.MX53 is, similarly like recent models of Voipac, available in 3 versions – Basic, Pro and Max. The key factor saying in favor of i.MX53 in comparison to competitors´ products is the price/ performance ratio.
A maximum hardware configuration contains literally all, what so small computer can offer. The module even contains a 3-axis accelerometer and a switch-mode power supply for user applications. For the i.MX53, there´s also available the development board (usable also for i.MX25 and i.MX51) and the multitouch capacitive display. The most simple way for development is to use complete reach-featured development kits. Voipac products are also extraordinary by the fact, that the producer supplies complete schematics and PCB from the Altium environment to every purchased development kit. Voipac provides an extensive support in a form of pre-paid 1 or 3-month support and in files free to download in a binary as well as source code.
Detailed information will provide you the i.MX53 flyer, i.MX53 datasheet as well as attached video. Further files can be found on the producer´s website in the downloads section (http://www.voipac.com/#Downloads).

Intelligent soldering stations WX series meet all what we might expect from an ultimate instrument.
The base of universal soldering and desoldering stations are WX1 a WX2 stations, with the possibility to connect 1 or 2 tools. WX1 enables to connect 1 tool with a maximum power of 120W and the WX2 station enables to connect two tools with a maximum power of 120W or one 200 W. An ultimate choice for rework workplaces are new WXD series stations, supporting the WXDP120 desoldering tool. A great advantage of the WX platform is a wide choice of tools and tips suitable for extra fine work with SMT components (WXMP tool, 40W), common work with the most of components (WXP65, WXP120) as well as for soldering of big joints and other components requiring a high heating power (WXP200). An invaluable helper at a work with components are the WXMT-MS (2x40W). SMT tweezers. WX tools are motion-activated through an integrated motion sensor. It means, that they consume energy only when they are actually in use.
Control interface of WX stations is done via a touch panel display. WX2 enables communication with other devices like control of WFE fume extracting station and a WHP preheating device.
The digital control electronics together with superior temperature sensor and heat-transfer technology guarantee precise temperature control at the soldering tip. High-speed measured-value acquisition gives maximum temperature precision and optimal temperature response under load. As we know, stable soldering tip temperature at the load is the essential condition to reach high quality solder joints independently on the joint size or type.

Right-angle LED indicators Kingbright L-1384 series provide a significantly more simple usage in comparison to standard wire-leaded LEDs.
If you have an application, where you need to solder LEDs with wire leads bent into a right angle or even to create a row of such LEDs, then the L-1384 series is the right choice for you. L-1384 consists of a LED assembled into a plastic housing in the way that the wire leads are in the right angle. The fact that the wire leads are shaped from production, eliminates possible damage of the LED at shaping by a customer (malfunction caused by an inner tension can occur after some time). Moreover, LED leads are trimmed to a length suitable for soldering to a PCB. Plastic housing from the non-flammable nylon (UL94-V0) contains a knop and a groove enabling to interlock LEDs to each other. It also ensures a simple assembly and a trouble-free creation of a uniform row. Black color also increases contrast of the LED.
L-1384 can be found in our offer, in a red, green a yellow color. A relatively low forward voltage in a range of 1.85-2.2V (@20mA) enables a trouble-free usage even in the low voltage applications. In case of interest in any Kingbright component, please contact us at email@example.com.
