These look like Motorola power transistors, but I'm not having any luck
finding information on them.
The label printed on the case is:
Motorola logo

Dear Friends,
I'm trying to find the pinout of the 2950CZ3.3 regulator without success.
This is a small 3.3 v regulator in a plastic cap like a transistor.
Can you help?

I got a APC Smart-UPS 700 that somebody was throwing out.  Works, only
it had bad batteries.  The question:  what output does it have --
"modified sine", or sine?  A quick lood at the APC web site didn't
reveal the answer, though it says not to run laser printers, so I

Hi, anybody know the standard for 0204, 0207 sized resistors and those melf
packages?

I've got this keychain from the 80'ies. It's a transparant plastic
thingie with a 16-legged chip inside.
I'm curious about what it is? On the chip is printed:
93415-DC

I've got some schematics published in this month's Make magazine. What a
hoot! Build an amp using a cereal box as the case.
So here's one of my first questions I hope somebody can discuss.
Does the type and capacity of a battery affect an amplifier's ability to

Hi, I am having a little microwave experiment, and I want to shield some
 cracks from leaking microwaves. A pal said to me that a paper-type
called "mica" is used for such reasons in microwave ovens. Actually what
he told me is that it allows microwaves to pass through, but it ...

I'm looking for a Licon/ITW catalog from the early 1980's.
Specifically, I'm in need of the pages which contain information
related to their 01-7 series and 76-71 series switches.
I've asked ITW and every distributor I know of for an old copy that

I am googling around for ultracapcitors/supercapacitors, and most pages
want to sell me a prefab "power module" or "request a quote".  Where is
the best place to order unit quantities of ultracapacitors of various
sizes for prototyping and general farting around with?

We are using FQU30N06L for a brushless control board, the MOSFETs marked F37
work fine as they have to do at 5 VDC, others  marked G21 do not work
because they start to turn on at 35 VDC. Someone had the same problem?
Ciao

In the past, for some switching assemblies, I have on occasion taken
advantage of the IR HexSense FET's. Big advantages at moderate currents of
not needing an external sense resistor, at the 'cost' of needing an op-amp
to generate a reasonably accurate current sense result, some ...

Anybody knows how much a typical SOIC8 chip weighs ? Also, how
much does the packaging (tube of 98) weigh ? The device of
interest is AD's AD82AR.
