ranatungawk New Member Sep 7, 2010 #1 if i replace a bad capacitor with a new cap with same capacitance and high voltage than the old one... can anything go wrong ? ex: bad cap value is 10MFD & 10V.... i'm going to replace it with 10MFD 50V one.....

JimB Super Moderator Most Helpful Member Sep 7, 2010 #2 Quick answer - no, it will be OK. Longer answer. For an electrolytic capacitor, I have an idea at the back of my mind that they work best when operated at 40 to 80% of their rated voltage. Does any one else here on ETO have any thoughts on this.

Nigel Goodwin Super Moderator Most Helpful Member Sep 7, 2010 #3 It will be perfectly fine, and probably better than the original - higher voltage electrolytics usually have lower ESR. The small size of 10uF 63V means that's the only voltage I ever stock - for 1uF I only stock 100V.

C cowana New Member Sep 7, 2010 #4 The closer you are to the voltage limit, the higher the leakage will be. The idea at the back of my mind is that high voltage capacitors have lower ESR used at the lower voltage, but that could be wrong. Andrew
