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.

1DFO SERIES - LOW DISSIPATION FACTOR

561C Series

Application Range: 500 Vrms; 1000 Vdc

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

up to 500, 1000, and 1500 V

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.

For convenience, power rating charts are shown to 100 kHz.

Higher

frequency operation is permissible with appropriate derating.

Consult factory for application suggestions.

Note 2

APPLICATIONS:

• Fluorescent Ballasts

• Industrial Electronic Systems

• Switching Power Supplies • Snubber Networks

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.
