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.
Operating Temperature: -40 °C to +75 °C Storage Temperature: -55 °C to +90 °C Operating Life: 40,000 hours with 95% survival with proper derating Dissipation Factor: 0.02% maximum
Case Material/Finish: Oval Case & Cover: Unpainted Aluminum
Rectangular Case & Cover: Unpainted Steel
Terminations/Hardware: 1/4 - 20 screw thread studs (60 A RMS maximum)
3/8 - 16 screw thread studs (100 A RMS maximum) Case Styles C* and D* have 100-A terminals. Nut and washer hardware is supplied in bag
Dielectric Fluid: A97F8600/ A97F8700 series: Dielektrol VII Internal Protection: These capacitors do not contain an internal protection
mechanism. The user is responsible for ensuring that the capacitors are correctly applied for safe use.
