In a surplus components grab bag I've found some resistor shaped
capacitors. They appear as normal 1/4 Watt resistors of a yellowish
colour and show two gold bands. Their value is also represented using the
normal color code adopted for resistors.

what is the proper procedure to find
integrated circuits that have the number
on them erased?
i need the microprosesor on a SRC-193

I recently had an outdoor Rainbow [LED] Lamp
apart to repair it (it recharges with usual
solar panels).  It is one of these LED lamps
that cycle continuously through red, green and

I'm designing the analog front-end for a device that measures EEG
(approximately 0.5 to 50 Hz, 10 to 1000 uV peak-to-peak). I'm using a
good instrumentation amplifier, and a good input RC network that does
not degrade the CMR.

I know very little about the technical side of electronics but I can use a
soldering iron.    I have two external hard drive cases which use what
"appear" to be identical power supplies.   Said power supplies reduce the
current from 240volts AC to the required supply for the hard ...

Hello,
Was wondering if someone might be able to suggest a cross reference for a
Analog Devices AD542KH which is long obsolete?
Datasheet:

Anyone know of a good source for Electroluminescent panels that has off the
shelf inventory and will sell smaller qtys of the stuff?
Seems every thing I encounter are manufacturer sites that have no info on
product availability...how to buy...etc.

I'm searching for the pricing of MEMS magnetometers... for example the
one used in iPhone..
How much does it cost?
Any links please?

I am looking for equivalents for the following transistors;
Does anyone know of a web site that will give me this information?
Thanks

At first glance it looks like a 2-terminal SMD package. But there's
what look like side terminals but AFAICT they're not soldered to the
PCB. (Or am I mistaken about that?)

Hi does anyone please have a pinout/datasheet for a TL2262R?
I've bee going 'rond in circles trying to find it on the net.

Anyone here have a possible source for a replacement Power Supply Board with
model number LM004 Rev 3??
I don't see a mfg. on the board but it is for a Vernex 17" LCD monitor.
Any help would be appreciated.

I often see references to these phone plugs RJ9, RJ10, RJ22.
It turns out those are non-standard names for a 4P4C connector.

What are the people who use these names likely to mean?

It's a bit more than the usual voltage. The MPSA44 / 94 JUST makes it
but the datasheet doesn't give hFE @ low Vce and the '94 seems to be
rare.
Any other candidates ? Cascoding could be problematical in this
