Type WMF Polyester Film Capacitors

Film/Foil, Axial Leads - Commercial, Industrial Applications

Specifications

Type WMF axial-leaded, polyester film/foil capacitors, available in

a wide range of capacitance and voltage ratings, offer excellent

moisture resistance capability with extended foil, non-inductive

wound sections, epoxy sealed ends and a sealed outer wrapper. Like

the Type DMT, Type WMF is an ideal choice for most applications,

especially those with high peak currents.
