Capacitors For Power Electronics(Energy Storage)
ESAS/ESBS/ESCS/ESFS
Energy storage capacitors
Dry type, Metallized film, Energy density up to 1J/cc
Series ESDS
General
The ESDS series capacitors are specifically designed for discharge applications. The capacitor has low losses and elements are made by self-healing metallized polypropylene film with dry technology. The special composition of polymeric dielectric enables to reach high dielectric strength and energy density up to 1J/cc. Special construction of connection terminals provides low self-inductance. The capacitors have excellent operating current and lifetime.Characteristics
