Realistically it seems like a component problem that the vendor is trying to blame on our processes. The problem is internal to the 0805 resistors so I suppose they are perhaps porous to some degree. I have only heard 3rd hand about the analysis that

14,000 uf now that's a BAC!!! Your thinking is correct. Connecting capacitors together works just opposite to connecting resistors together. * Capacitors in parallel add like resistors in series [Ct = C1 + C2 + ... Cn]. * Capacitors in series add l

Pictures are now located at http://www.stevezeva.homestead.com/ These components are 2W resistors that only see 1/2W at max. during normal use. I have contacted IRC still wqaiting for a response. The resistors were tested as good. But the circuit

Three LEDs, 3.5volts @.02amps each is 10.5volts. You said you calculated out an 82 ohm resistor so 82 ohms * .02amps is 1.64volts, I guess your going to use a 12volt supply. P=I*E =.02amps * 1.64volts =.033watts so a .25watt resistor will be fine

It gets tricky when resistors that your customer specified are no longer marked, but they think that unmarked resistors are a defect, and the manufacturer hasn't updated their data sheet to show the parts as unmarked, so you don't have anything to sh

Peter: This isn't what you asked for (I think), but it may be neater. Source of SMT links (jumpers): Most resistor suppliers make zero ohm resistors. Size � 8mm - 10mm (.312in -.4in) long: Most resistor suppliers package these resistors in comm

You are correct. The resistors are for personal safety. However, I don't think that bench top or floor mats require a 1MO current-limiting resistor. This would be necessary if a wrist strap was being used. The mats we use do have a 1MO resistor o

hi, I am a Hardware designer . One of my products is undergoing a Reliability test in which a resistor shows a high value on board from its specified value .However it retains the original value when its cooled under room temperature. The resistor

Thank you ENIAC for your comments Here is another problem (JUKI KE-750L) Which applies to 0603 (1608 metric) resistors and only resistors (mind you the board is more heavily populated with resistors) After the panel has gone through the oven, Wh

Yageo announced their decision to stop marking SMD resistors back in 2013, and since then we have started to see 0603's that aren't marked, but larger sizes - so far - are still showing a value. 0402's have never been marked, and I doubt they ever w
