250 - 6,000 VDC

These high voltage capacitors feature a special internal

electrode design which reduces voltage concentrations by

distributing voltage gradients throughout the entire capacitor.

This unique design also affords increased capacitance values

in a given case size and voltage rating. The capacitors are

designed and manufactured to the general requirement of

EIA198 and are subjected to a 100% electrical testing making

them well suited for a wide variety of telecommunication,

commercial, and industrial applications.
