    Need help identifying a component

    Think about it. Food dehydraters operate at about 140 degrees F. I've never seen one that operated above 155 degrees farenheit. 168 degrees C, is 336 degrees farenheit. You wouldn't be dehydrating at that temperature, you'd be COOKING the stuff. Any good appliance repair supply shop will...

    Need help identifying a component

    It's a thermal fuse. It's whole purpose is to open, so you don't have a fire. You BETTER replace it. The 169 degrees is in farenheit. The other letters are manufacurer codes for physical size and whatever else they wanted to designate. It's normal for those things to go. They're not...

    Moving my hand closer to the circuit changes it's frequency

    Can you shield the 4049, and connect the shield to ground? Most of the capacitance problems I've found that people think is due to their hand, is actually caused by EMI generated by electronics in the area, (transformers, flourescent lights, etc,... sometimes up to an including house wiring in...

    :( Motor problem

    You need to give us the faceplate information from the motor, voltage, amperage, and whatever else is given. You might need a rheostat (wirewound variable resistor), instead of a pot. With the motor and input voltage info, somebody will be able to help you on this site. If you're smoking...

    Military application idea

    *steve*, guess it would depend on who's air force it was. But I'm with you, if it was feasible, it'd already be in use. Joseph811, I'm not trying to be critical, I'm just trying to give you my 2 cents on what the potential problems might be (like you asked for). Some of the weapons...

    Military application idea

    Problems I can think of, are device by enemy to trip the RF return signal, thereby pin-pointing the location of all your soldiers on the battlefield. There is no signal that is so fast, an enemy computer looking for it, won't be able to find it. Honorable intentions, and good luck with coming...

    Signal generator and feed through termination

    When you're outputting an AC signal from your generator, the 50 ohm termination (you put it on the output END of the cable from your generator, TO the instrument you're sending the signal to. NOT AT the output of the generator itself), ensures a known constant load on the generator output...

    RCA VCR VR651HF Loading Motor Source

    I gave up fixing old VCR's. New ones are down to $40 where I am, you'll pay more than that for a replacement motor. If you're determined to fix yours, go on ebay, and buy your model, then salvage the motor out of the ebay one. With the prices of this stuff now, I'm glad I never got my own TV...

    Obsolete OEG series OUC relay

    www.newyorksemi.com shows some in stock. I've bought from them before, they did me ok.

    Antennas

    That's critical in transmitter applications, if you're involved in that at all. Full wavelength antennas would be very long, 1/2 wave half as long, 1/4 wavelength antennas, just like you'd think, ...1/4 as long. Most mobile radios use 1/4 wave antennas, to cut down on the physical length of...

    IC's number

    No. Some people like to think you can figure it out from the components around it. Somebody might be able to help you, if you give us the model number, and any identifying information on the printed circuit board, that might identify the component you're trying to identify. Like, is there a...

    capacitor replacement...

    I remember your original post about the zero, now. I also remember you saying something about when your meter zeroed, and when it didn't. Are you sure when you're touching your soldering iron to the parts and have them zero that it's the heat? Consider the possibility it's the grounding...

    Best precision DC power supplies

    You might look at Agilent. Xantrex changed to Sorensen, but now they're going by the name Ametech, or something like that. I don't know your application. The Sorensen people won't give you any info if you need to repair them yourself, you have to send the units back to them. You can get...

    Hakko 472 component values?

    I don't have the info you need, but wanted to add a caution to think about when you do this. Hope you get the schematic you need. OFTEN times, a printed circuit board that is stuffed for one model of a device, that is also used for a second model of the same basic device. Will have a few...

    Just Asking about resistors

    Not sure I'm understanding your question as you intended. A resistor is a passive device. Older resistors were commonly made out of carbon, nowadays also made out of other materials. A transistor is a semiconductor, not a passive device. Most transistors are made with silicon, because you...

    capacitor replacement...

    Normally no. I'm assuming this is just an electrolytic in a power application. Things get touchy in frequency sensitive circuits. Then the compostion and values of the capacitors come into play. (Resistance/Capacitance timing). Don't ever replace a bad cap with a lower voltage than the...

    IC's number needed

    Might help if we knew mfgr and model number? (of the inverter)

    Led power indicator help

    I don't know what a lag switch is. I don't know what voltage you're operating at, or what power you might have available through your push switch. If I was you, I'd take out your push-button switch, get yourself a simple on/off toggle switch, and then you can look at it, and know if the switch...

    AC Wall adaptor 9VDC 1A - Question

    Unless there's something particular about the circuit you're driving, it shouldn't hurt it. Think about it like your power from the wall socket. I'm on 120VAC, I can run a 3W lightbulb or a 300W lightbulb from the same socket. The 1A rating IS the max rating, not what you NEED to run your...
