(oh yeah, I've gotten some lower valued caps there before, and they were Fu Lee brand.)
I was wondering the same thing regarding ESR. Is 0.02 ohms for a 20k uF cap a reasonably good value?
Dr. Photon said:If you want a low ESR, you might want to consider paralleling several caps, or several smaller caps. You might also consider a small film or ceramic capacitor in parallel to maintain a low ESR at high frequencies.
You're right to be confused here. ESR is frequency independent. Impedance isn't.ohenry said:
I'm still a bit confused regarding the "low ESR at higher frequencies" statement.
