High Energy Density, High Temperature, Inverter Capacitors

Conventional film capacitors for power electronics applications (especially automotive) rely on polypropylene film, which is limited in how thin it can be extruded and begins to fail at temperatures exceeding 85º centigrade. Sigma, using its VaporFilm™ technology, is able to "extrude," dielectric films that are stable at temperatures exceeding 140ºC, are self-healing, have higher breakdown strength, and are up to 10x thinner than the thinnest polypropylene film available on the market today. The result is a high temperature inverter capacitor with greater than 5x energy density of even the smallest polypropylene film capacitor with the same voltage and capacitance rating.
