## Frequently asked questions

### How do I wire this electrolytic capacitor correctly?

Connect the positive lead (the longer one, or the side marked +) to the more positive point in the circuit, and the negative side (marked with a stripe) to ground or the lower-potential point. Reverse polarity can overheat or damage the capacitor.

### Is 400V suitable for a rectified 230V mains DC bus?

Yes. 230 V AC mains rectifies to a peak of about 325 V DC, so a 400 V rating leaves a safety margin. Always check the peak voltage of your circuit before selecting a capacitor.
