Frequently asked questions
Is this capacitor polarized?
Yes. Aluminum electrolytic capacitors must be installed with the correct polarity. Reverse voltage can damage the capacitor, so follow the marking on the case.
Is 25V suitable for a 12V supply?
A 25V rating gives margin above a 12V supply, which is a common choice for electrolytic capacitors on 12V rails. Make sure the rail voltage never exceeds 25V.
