GE Capacitor A97F8600 Series, A97F8700 Series Catalog Page

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 recom­mended 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.

SPECIFICATIONS

Available Capacitance Range: 1 to 50 µF
Capacitance Tolerance: ± 10%
Capacitance Variation with Temperature: ± 3% from -55 °C to +85 °C
Rated Voltage: See Ratings Tables. Rating is the Maximum Peak voltage

permissible in either polarity.

Rated Current: See Ratings Tables. The value given is for derating purposes

only. Refer to the Application Note on Page 12 to determine
the required derating. In no circumstances should the RMS
Current rating of the terminals be exceeded.
