A28F5000 Series Snubbers Capacitors 1000 and 2000 Volts Peak/ Max DC
The A28F5000 series of Snubber Capacitors are designed for use in power semiconductor circuits to protect the semiconductor
by limiting the rate of voltage rise. The dielectric system is polypropylene and paper with foil electrodes. The RMS currents encountered in these circuits are usually low; however, the peak currents are very high. Refer to the Application Data for correct application of these capacitors.
SPECIFICATIONS
Available Capacitance Range: 0.05 to 2 μF
Capacitance Tolerance: ± 10%
Capacitance Variation with Temperature: ±3% from -30 °C to +80 °C
Rated Voltage: See Ratings Table. The 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 10
Amp RMS Current rating of the eyelet terminals be
exceeded. For 1/4-20 threaded terminals, full current less
any derating may be applied.

Operating Life: 40,000 hours with 95% survival with proper derating
Dissipation Factor: 0.3% maximum
Case Material/Finish: Aluminum Case with Steel Cover for eyelet terminal designs;
Aluminum case with Aluminum Cover for *Threaded
terminals.
Terminations: 0.125-in. Solder Eyelets (10 Amp RMS maximum) & 1/4-20
screw thread studs (60 A RMS maximum) For threaded
terminal designs, nut and washer hardware is supplied in bag
Dielectric Fluid: A28F5500 Series Dielektrol VII
A28F5600 Series Dielektrol VII
Internal Protection: Internal Pressure Sensitive Interrupter for eyelet designs.
Threaded terminal designs do not contain an internal
protection mechanism. The user is responsible for ensuring
that the capacitors are correctly applied for safe use
