Vishay ESTA

STANDARD CAPACITORS IN CYLINDRICAL CASING, OIL IMPREGNATED, SELF-HEALING, WITH FUSE

DC CAPACITORS

Series GMKP 1000V - 3000V, higher voltages upon

request.

Capacitance range 1-400

µ

F, in relation to rated

voltage and dimension. Other capacitance values,

upon request.

GENERAL

VISHAY ESTA DC-capacitors may be loaded with a

comparatively high component of alternating voltage or

alternating current due to the low ohmic and low dielectric

losses. Thus the capacitors can equally be employed for all

DC applications.

The capacitors can also be applied as AC capacitors at a

rated frequency of 50 Hz for the quoted root-mean-square

voltages.
