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.

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
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.
For convenience, power rating charts are shown to 100 kHz. Higher
frequency operation is permissible with appropriate derating.
Consult factory for application suggestions.
