Frequently asked questions
Can I replace it with a higher voltage capacitor?
A higher voltage rating than the circuit requires is generally acceptable as a replacement. Never use a lower voltage rating than the circuit needs.
How do I identify the polarity?
Electrolytic capacitors are polarized. The marked stripe usually indicates the negative lead, and the longer lead is normally positive. Connect the positive lead to the higher potential.
