Anyone know of an online source of data fot this elderly Infineon chip.
My Googling has only turned up the usual hoardes of shysters trying to
flog off truckloads, but no data or pinout. It's in an ancient
Sennheiser impedance meter.

Are you a IC buyer, seller or trader?
Boring about the IC Price?
We could provide you a IC Price Access Database for your reference.

I am trying to source an L4963 ( no suffix) switching regulator chip to repair
a home control
PC board.
Unfortunately everyone I have been able to track down as having these will only

I have a hirose connector (a type HR10A plug with soldering cups).
One of this series...

I would very much like to solder a cable to this damn thing, but I

After about 8 years using dozens of NiMh cells I have now had a single
failure of one of the early AA cells where normal charging wouldnt
pull it back.  I did the old capacitor discharge trick we used to use
on NiCd cells and that worked immediately. (32,000uF I tried set @12v)

Nowaday, it is difficult to find BUX84, BUX85. Any expert here know
why. Is it being replaced by other series of NPN transistors.

I need a relay to switch 110AC using 24VDC.  It should be normally
open.  I get confused looking at all the specs.  What kind of relay do
I need?  Is SPDT the right type?
Any help and links to source is greatly appreciated.  I am looking for

Is there such a thing as a jellybean 74- or 4000-series part that takes
a binary or BCD input and drives a bar graph LED from it?
I need to drive an 8-LED bar graph from a 4-bit data source with the
minimum of components, and right now the simplest option appears to be

I have been given 21 new sample pieces of Kionix KXM52-L20 3-axis 2G
accelerometers. The datasheet for these is at
http://www.kionix.com/Product%20Sheets/KXM52%20Series.pdf.
These devices are in DFN, which is a very inconvenient package for me.

I saw color rings on the diode, which is yellow, brown , yellow and
grey. I know this is simply a diode. what does the color means. Thanks

How does the capacity of a Duracell-brand AA cell (Duracell ordinary
or Duracell ultra) compare to one of the high-capacity NiMH cells (eg
2100 mAh)?
I am assuming, of course, that any applicance using the cells would

I've an AMREL power supply that have its rocker switch gone.
I've tried email them twice to have either the switch ref or a replacement
part but they never bothered to answer (despite their claim to answer every
email within 24h)  :-((

I'm looking for an IC to generate a simple pleasant tone to use in a medical
product.
The tone will be for a patient call button. A simple chime or pleasant gong
will do.

Is there a crossref between the Federal Inventory Number and parts such
as semiconductors?  Maybe I should say, I figure that there such a
thing, but is it available to the public, and not just gummint?  I
haven't done any searches for such a xref, mainly because it's probably
