Heh, yeah I know they were suss (or a con. take your pun ;) ). Replaced the six of them, and the monitor the board was pulled from works!   :-+ :scared:

<Baljem> hey, you're the one who apparently pronounces FPGA 'fuhpugger'

Thats a good abbreviation for suspect condensers.

 most likely a Infrared sensor (infra red sensor- infra-red sensor- IR sensor). For use with PICAXE circuits to detect infra-red signals from a TV style remote control or another PICAXE chip. 2.7V to 5.5V operation.

I've got an insultingly simple one - what's the name of this? I bought them from god knows where on eBay, just called "2.54mm headers", and I want a name to put them in my component library under. They're ridiculously common, so someone's got to know a proper name for them!

I dunno, I'd think "header" would be a perfectly appropriate name for it.

Would a "shrouded header" be enough? I didn't want to use 'header' because it's bigger than an unshrouded one, so it needs a bigger courtyard and thus a different footprint.

Is it not just referred to as a 2.54mm Molex connector?

JST "XH" connector. Spacing is 2.5mm (close enough to 2.54 that it doesn't matter unless you have a high pin count connector)

Does anyone know the name of this connector? Never seen that before. Guy from my work said that they received PH electrodes with such connectors but without any wires. I think it's some surplus, damn cheapskates. Now they don't know what to do with them.

It looks a bit like a Siemens coax connector.

Any one know what this is please, the one on the left in the photo. with the sil pad, it says D288 on top and Y-920 at the bottom, one leg appears to be open and I am not sure if its a transistor or back to back diode, its from a scope power supply. Google does not come up with it but does with BD288.

When in doubt, add "2S" before the name of what looks like a transistor

Holy crap, i thought that was part of the part number! I mean, you never see transistors in to-220 packages with to-220 written on them ect! I feel dumb :(

It's also part of the part number. Those bridge rectifiers are so common that the manufactures simply use the package, amps and voltage as part number.

I need some tac switch extensions, but I do not know what they are called. I have a board which has a number of tac. switches on it that I want to mount in a case. I have seen these devises which mount on the case to make contact with the board mounted switches but no idea where to look as I do not know the correct name.

They seem to be called "extenders" or "plungers". Here's one:

and here's a bunch more (not all for tact switches):

It is a thermistor unit, and is normally used in self heating mode to provide stabilisation of analogue circuits. They are commonly used in Wein oscillators to keep the loop gain constant and so generate a constant amplitude sine wave.

Another use is as a temperature sensor in amplifiers to keep the bias constant with external temperature changes.

I was going to use one when I made an ESR meter, but instead used a 28V grain of wheat leaded lamp instead as a PTC. Still have a few around in a box somewhere. I just had to look thorugh the box of assorted leaded lamps and test a few of the mixed ones to sort out a 28V one. Took 3V from 2 AA cells and tested lamps to find those that did not glow ( the glowing ones were the 5V ones) then tested the dark ones on 12V to get the non glowing again ( 12V lamps0 and finally checked them on 24V to see if they still worked. Took the first one and used it and put the rest back in the box mixed as before.

Hi I have a TO220 package on a chinese PWM motor controller labeled STPS205100CT,  G40N2 and CHN305 I have tried Google but cannot find any info on this device, in fact all it seems to bring up is dodgy Russian web sites with links to other even more dodgy Russian porn sites. Any one have an idea as to what this device is please.
