About this product
Electrolytic capacitor rated 220 µF at 35 V. It is used for filtering power-supply outputs, smoothing ripple after a rectifier, and decoupling DC rails where a large capacitance is needed. Observe polarity and choose a voltage rating above the maximum voltage in the circuit.

Frequently asked questions
Does polarity matter for this capacitor?
Yes. Electrolytic capacitors are polarized: the negative leg must be on the lower-potential side. Reverse polarity can cause leakage, overheating or failure.
Which voltage rating should I choose for a 12 V circuit?
Use a rating with a safety margin above the circuit voltage, so a 35 V rating is a common choice for a 12 V rail. Ripple and voltage spikes should also be considered.
