In the home environment, they are used in home theater systems, computers, video games, cable television, home security systems, and many other electronic devices.

Working Principle

Film capacitors achieve their functionality by combining two metal plates. The space between the two plates is filled with an insulating material, known as a dielectric. Through this dielectric, electricity can be stored and conducted. In the case of the 150394K100EB, the dielectric is a polyester film. The edges of the plates are encased in a plastic or metal film capacitor enclosure, which acts as a shield to protect the plates from external damage.

The two metal plates of the capacitor are responsible for storing the electrical charge. When voltage is applied to the capacitor, an electric field is created between the plates and the electric charge is stored. The dielectric material provides insulation between the plates and helps maintain the electric field, thus allowing the capacitor to store more charge at a given voltage. The 150394K100EB is a non-polar film capacitor that operates using a self-healing dielectric.

The self-healing dielectric has an ability to repair any damage that may have been caused to the insulation layers of the capacitor. This is due to the construction of the film, which is made up of multiple layers that are connected by carbon particles. If a puncture occurs to one of the layers, the surrounding layers shift to form a bridge and effectively re-seal the damaged layer, thus maintaining the insulation level of the capacitor.
