Type WMF Polyester Film Capacitors
Film/Foil, Axial Leads - Commercial, Industrial Applications
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.
Highlights
- Very high dV/dt
- Very high peak current
- Low inductance
