97F7500 Series SCR Commutation Capacitors

250 Volts Peak

The 97F7500 Series is a special purpose line designed for

applications where a large micro-farad value at low voltage is

required in a small size. The dielectric system is metallized

polyester. Typical applications are in SCR chopper circuits and

low-voltage ac filters. Refer to the Application Note on page 12

for assistance in the correct application of these capacitors.

Please note that previous offering of these capacitors was

with painted cases, to improve heat dissipation. The units

will no longer be painted as part of GE’s committment to

environmental programs. Please note the change in RMS

current ratings from previous catalogs.
