Electromagnetic near-field PCB Probes are open source
https://www.electronics-lab.com/electromagnetic-near-field-pcb-probes-are-open-source/
In modern compact electronic circuits, there are several components on a confined PCB area, and so, the electromagnetic effects induced from one component may affect the surrounding components. This disturbance is known as Electromagnetic Interference (EMI). The source of the radiation must be identified in PCBs to predict the EMC of electronic circuits. Electromagnetic compatibility (EMC) […]
Coilcraft Releases Power Line EMI Chokes in 16 Sizes/Configurations
https://www.electronics-lab.com/coilcraft-releases-power-line-emi-chokes-16-sizes-configurations/
Coilcraft offers the Cx family of surface mount, common mode EMI chokes. There are 16 sizes and configurations to meet the design needs of a broad range of power line circuits, says the company. They suppress high frequency common mode noise up to 100MHz and offer greater than 40dB common mode attenuation, making them particularly […]
Isolated Power Supply for RS485, RS422, RS232, SPI, I2C and Power LAN
https://www.electronics-lab.com/isolated-power-supply-rs485-rs422-rs232-spi-i2c-power-lan/
Mini Isolated Power Supply is designed for CAN, RS-485, RS-422, RS-232, SPI, I2C, Low-Power LAN applications. The power supply provides +/- 5.50 V DC symmetrical outputs with load current 500mA from 5V DC input. The project is built using SN6505A IC from Texas instruments. The SN6505A is a low-noise, low-EMI push-pull transformer driver, specifically designed […]
The behavior of electro-magnetic radiation of power inductors in power management
https://www.electronics-lab.com/behavior-electro-magnetic-radiation-power-inductors-power-management/
Application note form Würth Elektronik about EM radiation radiated from inductors in DC-DC converters. This Application Note focuses on the Electro-Magnetic (EM) radiation behavior of power inductor(s) in DC-DC converters, which is dependent on several parameters such as ripple current, switching frequency, rise & fall time of a switching device, the core material and its […]
Radioactivity detection using very simple ionization chamber
https://www.electronics-lab.com/radioactivity-detection-using-simple-ionization-chamber/
Robert Gawron tipped us with his latest build. He writes: Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It’s also immune to electromagnetic interference (EMI) due to a good shielding. Radioactivity detection using very simple […]
