Frequently asked questions
How do I know which lead is negative?
The negative lead is marked on the capacitor body with a stripe or minus signs. The longer lead is usually positive, but always confirm with the body marking before soldering.
What voltage rating should I choose for my circuit?
Choose a rating above the highest voltage the capacitor will see. This 400 V part is suited to circuits below that limit with a safety margin. Do not exceed 400 V in operation.
