An electrolytic capacitor is a polarized electronic component that stores electrical energy using an electrolyte-soaked material as one of its plates. It is widely used in power supply filtering, audio circuits, and other applications requiring large capacitance values. While they offer high capacitance in a compact size, electrolytic capacitors are known for their limited lifespan and tendency to fail or leak over time due to the breakdown of the electrolyte. Proper orientation and voltage rating are crucial for safe operation.
