Slightly off-topic, but it's a question people here might know better than
anyone on the planet.
I'm after a Class 1, bluetooth v2 (must also do v1.2) adapter for serial
ports (DB9). Needs SPP profile, no other profiles required, but they might

What are people's favorite low-dropout linear regulators?  ("Jellybean" in
the sense of The Art of Electronics -- the ones you want to keep on hand in
some quantity.)

I need a Temic U4224B chip, which is used for reception of DCF and
WWVB time signals at vlf.
Are these available without going to Europe?
Thanks,

Hi fellow engineers,
I am designing an FPGA board and I want to include an optoelectronic
interface on the board. What I have in mind is a 1-channel optical receiver
module (digital data output), packaged for integrating directly on-board

Who sells SnAgCu solder, preferably small diameter with no-clean flux, in
packages smaller than a 1-pound roll?  Anyone?  The lead-free stuff
available in small quantities seems to be SnSb.

I just found another box of misc. stuff cleaning out my lab (Thanks to
the person who asked here about SD cards the other day). If anyone's
interested, email me otherwise I'll try and get this stuff listed on
eBay over the weekend.

Hallo Leute,
Gibt es bei Euch Erfahrungen mit diesen Geraeten?

Wobei es eher um die 6010/6011 Geraete geht, denn die 5010/5011 Serie

We are popping across the pond for a few days, are there any decent surplus
electronics places in the Phoenix area ??

I'm trying to build a handheld gaming device using a PIC16F887 with
an
LCD screen.
Although the PIC will run at lower voltages the LCD requires 5V.

I have been using the Analog Devices AD9501 programmable delay chip in
some gear, and was planning on designing a new board with them when I
discovered they were obsolete, and becoming scarce.  The chip is just
about ideal for what we are doing, and I've found nothing that comes ...

I'm looking for an instrumentation amp to be run on a lithium battery (3V).
I need low power consumption and a common-mode input range (CMIR) of as much
of the "power supply" as I can get.  All of the IAs I've looked at so far
- TI, AD, LT, good grief I've even checked out Maxim's ...

What would be a really low noise FET? Should be well under 10nV/rtHz at
the lower end of the audio band, say at 20Hz. Ideally 5nv/rtHz. Looked
at former Matsushita parts, now Panasonic:
2SK3426: Supposedly good but no specs to wrote home about.

I am looking for replacement for an BCX42 PNP transistor that got
damaged in an LCD inverter.
The FMMT555A in mouser.com seems to be an ideal candidate, but the
datasheet has all the voltage in negative number(for example Vcbo

Does anyone knows a replacement equivalent for the MOTOROLA SRF-3999
RF MOSFETs?
Thanks in advance

Most of us know the old uA733, it's still sold but the quantities aren't
very encouraging. A whopping 34 pieces at Digikey. Big red flag for me.
The NE592 is non-stock in all versions and there are a few thousand
TL592. None of these were ported past SO style. That's another ...
