Electronics Forum / Components / January 2007

This may seem like a stupid question, but I've been wondering this for quite
a while now, and I hope someone here can help me answer this:
When you go looking on the web for a source to purchase some part, and you
can't find it in any of the usual vendor's catalogues (i.e. Digikey, ...

I Have a qustion to those familiar with 1-2" OLED displays.
I find both displays with analoge RGB interface and some with digital
RGB interface and my question is therefore:
-is the technique/coding used for drawing up the image (colours) on

The usual: Just about to finish a design. When I started a week ago the
LP324PW in TSSOP was in stock, now it's gone. Bone dry out there.
Minimum leadtime now four weeks. Drat. Does anyone know where to get
some? For prototyping we only need a few.

A client of mine needs TO-5 10-pin sockets, often called TO-100. For
example Keystone Cat.No. 4594. They are commonly used for small VCSEL
lasers with integrated thermo-electric coolers. But not much for ICs
anymore and that seems to be the problem.

Says on their site: "Back by popular demand - Classic Search". Hmm,
interesting. Seems there is finally a company that did listen or was
willing to admit that they blew something.
The "In Stock" check box is still a bit iffy in that it occasionally

Folks, what's the most prevalent pinout convention on SC-75 packages?
The Rohm 2SK3019 is one of them that I'll use and it's:

Anybody know where I can get some non-italic 7-segs? Or is there another
easy solution?

Originally posted in Sci.Electronics.Repair, but everyone wants to
dance around my question. Does anyone here have the answer?
Can you tell if a capacitor has leaked by dissecting it?
My JVC stereo is humming loudly. There are signs of an obvious

Can you tell me what customized transformers are in high demand?
Is transformer in lot of applications?
What area of the electronics product design do we find many requirements of
transformers?

I'm looking for MEMS relays.
I found 3 manufactures who does such things: TeraVicta,Memtronics and some
other..I've written some mail to them, but till now - without response..
So I wander, if U know some other source of such components...

I have an IC:
NEC 42505C-50
Unfortunately I didn't find any datasheet on the net.
Does anybody know its function

It's bewildering. Was looking for diodes in SC-75, barely anything. Then
by chance I found the beloved old BAS, BAV and BAT diodes again.
Slightly different numbers but they were listed under SOT-523 which
looks the same to me as SC-75, or SOT-416 for that matter.

While attempting a home-charge of a set of NiCd batteries, they were
left unattended and consequently exploded (relatively high current was
flowing through them). The basement area in which the explosion took
place is currently being ventilated overnight.

All right here, much great/useful stuff & very inexpensive>

I'm trying to get started with some projects and need a reliable source
for components.
I've done some looking around the web and came across Jameco,
Tycoelectronics, and Digi-Key.
