Capacitor encapsulation materials

Basic Knowledge of Film Capacitors

The demand for inverters used in environment-related equipment such as EVs/HEVs and solar/wind power generation systems is expanding in the capacitor market. For such applications requiring enduring high voltage exceeding 500 VDC and long-term use for several tens of years along with a high level of safety, demand for film capacitors is increasing.

Encapsulated Capacitor

Electronic encapsulation materials are chosen for their ability to insulate by three mechanisms: thermally, electrically and mechanically. Traditionally, such materials have included polyesters, cellulosics, or even thermosets. Each material has its limitations, and none proved capable of meeting all of Accumold''s needs. Foremost, it was essential that the material flow well and be
