This makes no sense!
Is the pcb double sided? Is the pcb powered when you are making the measurements? You could try swapping the resistors and measuring again. Is your multimeter working ok? Have you...

USB Battery Charging
If you can handle low charge rates, you could just use a high temperature rated NiCD or NiMH and charge it at 0.05C using a resistor and a diode. Good quality high temperature...

Four switch positions, two AVR inputs
Not sure if this helps. Just connect the switch net to either A, B, C or D. I've put the opto in, you could run this opto low or high side into the AVR depending on what you...

molex type connectors with 3mm or less pitch
TKP make this part. Not sure if you can find a distributor.

Question on TVS diode
Ambient temperature of 125'C sounds challenging.

Breakdown and standoff voltage for TVS diodes in 3.3v system
Can't you just have the TVS diode then a series resistor to the mcu (perhaps a capacitor also for some extra filtering)? Use a 3.3V TVS then a 10k series resistor. This way the...

MCUs with USB in DIP package other than PICs
Perhaps have a look over at Holtek?

Filtering ESD for CE compliance
I agree with Jim. I think you should check out the capacitance you have. TVS diodes can help to clamp levels to safe limits. Layout will be another thing to check. You need to...

Driving 24 LEDS with a attiny 44
LDEVRIES, The gates will have capacitance, so there will be some current on pin changes. I do agree regarding some sort of gate-gnd protection. oddbudman
