Kemet Capacitor: Understanding the Basics and Applications


Kemet Capacitor is a leading manufacturer of capacitors, a crucial component in electronic circuits. Capacitors play a vital role in storing energy and regulating voltage in various applications. In this article, we will delve into the world of Kemet capacitors, exploring their types, characteristics, and applications.

What is a Capacitor?

A capacitor is a passive electronic component consisting of two or more conductive plates separated by a dielectric material, such as air, ceramic, or a polymer film. When a voltage is applied across the plates, the capacitor stores energy in the form of an electric field. Capacitors are commonly used to:

Filter or regulate voltage

Couple or decouple signals

Store energy for later use
