SCR Commutation Capacitors

A97F8600 / A97F8700 Series

600 to 1500 Volts Peak

This family of capacitors is designed for high-current applications, such as

(1) SCR commutation, (2) snubbers for SCRs, GTOs and other power

semiconductors, and (3) for any other circuits where the combination of

frequency and voltage results in high RMS currents. An Application Note is

provided to assist in the proper use of these devices. It is strongly recom-

mended that users refer to GE engineers for assistance if there are any

questions as to the correct selection of capacitors. The A97F8600/

A97F8700 Series have an all-film dielectric and, due to the much lower

dissipation factor, can handle much higher currents than the older film paper

designs.

Advances in capacitor Dielectric technology have made paint

unnecesary, in most cases. This along with GE’s commitment to

environmental programs has led to the elimination of painted cases in

this product line. Removal of the paint has minimal affect on the RMS

current ratings; see the standard ratings charts for proper application.
