1DFO, 2DFO, 3DFO Series
Vishay Cera-Mite
Low Dissipation Factor Disc Capacitors
FEATURES
•
Ideal
for High Voltage Switching to 100 kHz
•
Low DF Minimizes Self Heating at High Frequencies.
•
Application Voltages: 500, 1000 and 1500 Vac.
•
Economical
Alternative to Film Capacitors.
The 1DFO, 2DFO, and 3DFO Series are designed to operate
up to 500, 1000, and 1500 V
RMS
, 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 30°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 3
Power ratings are based on still air 60°C ambient with additional 30°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.
For convenience, power rating charts are shown to 100 kHz.
frequency operation is permissible with appropriate derating.
Consult factory for application suggestions.
