Frequently asked questions
Does this capacitor have polarity?
Yes. Aluminium electrolytic capacitors are polarized. The negative terminal is marked on the body with a stripe or a minus sign. Connect the positive lead to the higher voltage side, because reverse polarity can damage the capacitor or cause it to burst.
Can I operate it close to its 450 V rating?
Avoid it. Never exceed the 450 V rating. For reliable operation, choose a capacitor whose voltage rating is comfortably above the maximum voltage in your circuit, commonly by 20% or more.
