Abstract
An electrical film capacitor in which a pair of metal film electrodes and a porous layer are wound into an assembly, and in which the porous layer serves to wick a liquid dielectric into the wound assembly. The liquid dielectric is an adipic acid ester such as di-isononyl adipate. Mono-isopropyl biphenyl can be added as well.
