What is a Filter Capacitor?
A filter capacitor is an electronic component that removes voltage or signal spikes in electronic circuits. Capacitors are used as filter devices due to their ability to absorb and effectively store electrical charges at predetermined values. This characteristic is used in a filter capacitor application to soak up or buffer voltage values which exceed set parameters. Filter capacitors are typically placed across a load or as a path to ground in circuits. Several different filter capacitor types include electrolytic, ceramic, and tantalum.
