Plastic Film Capacitors

The film capacitor varies significantly in the effect of washing depending on the structure and material, and generally it is less

affected by CFC or alcohol derivative washing solvent, and is likely to be affected by highly polar solvent.

The lead type film capacitor is coated with an epoxy resin excellent in chemical resistance, and is hardly affected by detergent,

but it is recommended to be washed for short duration.

Applicability of detergents in film capacitors is listed for reference.
