First of all, apologies for the off-topic question but I thought some of you
may be able to help. I'm looking for "6-32" threaded screws, whatever that
means. I've checked Farnell and RS (I'm based in the UK) and they mostly
have the standard ISO Metric (M3, M4, etc.) screws. I can ...

I am trying to find a surface mount bi colour (red / yellow) low current
(<2mA)
Led. I can find low current or bi colour but not both. Does anyone know if
such a thing exists and if so who manufactures it?

I checked my usual suppliers and no one has these in stock.
Does anyone have one, or know of a supplier that might have one in stock?
If so, please reply at shatter@odys.net with any info.
Thanks,

Does anyone know what this device is and a pinout?  I think it may be
Toshiba's equivalent to a 7915 -15V 3 terminal regulator, but it would
be nice to know before replacing it.  Toshiba doesn't make it anymore
and disavows any knowlege of the device.

I am constantly running into a need for a shift register in my designs to
convert serial to parallel data (or vice versa). Yet as far as I've found,
the most "modern" one available is the Fairchild 74AC299. It would be very
nice, indeed, almost mandatory, to find parts with more ...

Are there any of these Rabbit Ear/UHF loop combo style antennas with
the multi-position knob that attach to the coax fitting on the TV that
are actually significantly better than others? Is there anything you
can do to supe-up their performance?

Hello everyone! I have a question, I hope you can give me a possible
solution to this. I need an IC that reads a binary combination (dip
switch - 8 bit) and the transmit that combination using logic in
serial way. Do you know an IC that does that without any other

If a 100V aluminium electrolytic cap (say, 10uF @ 100V) is used on a 5V
circuit, will it be OK? I mean, will the capacitance drop or the performance
of the cap affected as a result of using it at a much lower voltage that its
rated voltage? Would it be better to use a 16V cap for ...

I've always known and admired the superior properties of Tantalum caps.
BUT... I've been reading posts in sci.electronics.* and elsewhere about how
they can turn into nice fireworks/explosives, or can fail easily under harsh
conditions. I've been looking at the so called "solid ...

I have had this component in my junk-box for ages, I probably unsoldered it
sometime in the '80s. Now I wonder if someone could satisfy my curiosity and
suggest its original purpose.
It is marked:

I was wondering if I could "integrate" easily a low-pass filter (for
ADC anti-aliasing purpose) in an instrumentation amplifier.
I would not want to include an active filter between the
instrumentation amplifier (the ADC buffer) and the ADC itself. Just

I am looking for the datasheets of Intersil and Harris CDP65C51 uart
chips. We were using Intersil CDP65C51AE4 previously and it worked
well. But after we replaced it with Harris CDP65C51AE4, a lot of them
do not work well on our boards. I tried to search for the datasheets

I need to switch a 12V/10A DC supply by a TTL logic.
I thought to use a triac driven by the MOC3043 optocoupler.
The datasheet of the MOC30xx is here:

Could someone plse recommend a supplier of the old fashioned multi-section
phenolic wafer switches, as have a broken wafer to replace in a
multi-section band change switch.
I need a switch having 2 pole, 5 position wafers, with wafers being 1-3/8"
