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 30C 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. 1DFO SERIES - LOW DISSIPATION FACTOR

Note 3
Power ratings are based on still air 60C ambient with additional 30C 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.
