For a logic level mosfet with RDSon specified at 0.09 ohms at about
10a, with VGS at 5V, will it act as a .09 ohm resistor even for low
currents, like 10 to 100mA, giving a drop of 1 to 10 mV, or is there a
voltage burden? The data sheets that have graphs don't show this area

PCBCAD17 is a great pcb layout package.

I've been trying out some of the various free schematic capture tools
(gschem, Weblab and various others), but none of them are really what
I'm after. Specifically, I'm looking for a reasonable spice GUI,
suitable for nanometer IC design with a good waveform viewer. I've used

I saw some pictures of those "tin whiskers", and I didn't know the
problem was so great.

So... is Airbus required to go for lead-free solder too, for RoHS and

I'm looking at PSS-2005, and PSM-3004 or PSM-6003.

Obviously, the PSM is much more power, a nicer panel, and also heavy!

I am in Singapore to find a job.
I used to be a PCB designer when I was in Myanmar.
And I need to study the PCB conceptions here.
I know the basis, however, what I do not know is with the things I need

They don't seem to have a website.
Going to www.cpclare.com gets you a generic site and Wayback blocks robots.
Did they merge or fold?
Need info on their product MRB 6A05

Our factory mission is repair systems; today we are working with a
Texas Instruments microcontroller marked TMS375c717FNL or TMS375c017.
This microcontroller is used on a balance system produced by Sartorius
a.g. (Germany company).

Can anybody please tell me the names of some famous universities of the
world which are offering the Masters in Circuit designing. I am not
asking about IC design but specifically the digital and analogue
circuits designing.

Only in Europe is Testosterone considered an illegal drug.  Does this
surprise anyone in the US?

I have an ICSP programmer supplied by the target circuit and I use a PNP
(2N2907) transistor as a reverse polarity protection. I put the emitter to
the target +5V, the base to ground through a 1K resistor, and the collector
feeds the programmer. I have roughly 0.02V drop out in ...

How come its so hard to find ADC's with more than 16-20 bits of resolution
with high conversion rate?(200kSPS+)
Ultimately I would like an ADC and DAC with ~32-bits at 360kSps for use in
an audio project... although I could deal with the minimum of 24bit at

I'm tinkering around with an idea that would require controlling some
hardware over a WLAN.  I've got lots of electronics experience, but
ZERO wireless experience.  Are their single chip (i.e. CHEAP) solutions
on the market that can plug into a design that handle the wireless junk

Possibly a current operated reed relay.
Also could be a SSR or Hall device.
Potted module.
Strange in that the two inputs seem much higher current than the three

Is there any reason that Supertex LR8 regulators cannot be used with
external pass elements in a similar way as their low voltage (LM317)
cousins in order to increase the available current ?. Looking for an
adjustable (50..350volt /150ma) regulator to run from a 400v raw
