Introduction

An electrolytic capacitor stores electrical energy and releases it when needed in electronic circuits. Its polarized design offers high capacitance in a compact form for filtering and timing applications.

  • Wide voltage range to suit various circuit requirements
  • Long operational life when used within rated specifications
  • Compact radial or axial packages for easy PCB mounting

Browse electrolytic capacitors by value and voltage.

FAQs

It smooths voltage fluctuations and stores energy in power supplies and audio circuits.

Yes, they have positive and negative leads that must be connected correctly to avoid damage.

Match the required capacitance and voltage rating listed in your circuit schematic.

Not always; ceramic capacitors usually offer lower capacitance and different ESR characteristics.

Overvoltage, high temperature, or age can cause leakage or bulging, leading to failure.
