ESR Meter project

ESR Meter project: Port over

Postby Mr. Nick » Tue Feb 08, 2011 2:40 pm
I would like to start a group project. I think designing and building some ESR meters would be a good one. I know that being in manufacturing you guys probably don't need to measure ESR all that much if at all on those new components. However I think it would prove to be a very useful personal troubleshooting tool.

I have an LC analyzer here at work and it includes ESR measurements among many other things. I find bad capacitors all the time at work. They are usually visually damaged (bulged and leaking goo). There are however many a capacitor that is not visually bad and still measures out to be the correct value of capacitance. The only thing that is different that causes the circuit to fail or malfunction is the ESR value.

Check out link for some info on ESR.

There is a nifty kit as well.... I don't know if that would be the better route.

Use this one: http://ludens.cl/Electron/esr/esr.html

I built one and it works pretty well. :D
