2DFO Datasheet, PDF (1/2 Pages) Vishay Siliconix – Low Dissipation Factor Disc Capacitors

1DFO, 2DFO, 3DFO Series

Vishay Cera-Mite

Low Dissipation Factor Disc Capacitors

FEATURES

â¢ Ideal for High Voltage Switching to 100 kHz

â¢ Low DF Minimizes Self Heating at High Frequencies.

â¢ Application Voltages: 500, 1000 and 1500 Vac.

â¢ Economical Alternative to Film Capacitors.

The 1DFO, 2DFO, and 3DFO Series are designed to operate

up to 500, 1000, and 1500 VRMS, respectively. Their low

dissipation factor (DF) and stable temperature characteristics

are well suited for operation at elevated frequency. Operating

limits are governed by a suggested 30Â°C maximum case

temperature rise as controlled by applied voltage and

frequency dependent current. Power-rating charts covering

the entire series provide operating guidelines for higher

frequency applications.

Note 1

Note 3

Power ratings are based on still air 60Â°C ambient with additional 30Â°C rise

due to self heating. Thermal effects such as forced air cooling, component

encapsulation or other heat-sinking techniques will alter ratings. Actual

circuit test is recommended.
