Oil filled capacitors are some of the most common types of capacitors used in electronics. They are found in everything from power supplies to signal processing chips. The two most common types of oil filled capacitors are paper and Polyester. Paper capacitors are the originals and were invented in 1921.
A capacitor is a passive electronic component that can store electrical energy. Capacitors come in all shapes and sizes, but the most common ones found in electronics are the electrolytic and the paper (or ceramic) capacitors. In this article, we’ll focus on the electrolytic capacitor. An electrolytic capacitor is a device composed of two conductive plates separated by an insulating material, which stores electric charge.
