Standard atmospheres conditions

Unless otherwise specified, the standard range of atmospheric conditions for measuring and testing is as follows:

Ambient temperature      15°C~35 °C

Relative humidity         45%~75%

Air pressure             86Kpa~106Kpa (860-1060mbar)

If there may be any doubt on the results, measurements shall be made within the following limits:

Ambient temperature      25°C±1 °C

Relative humidity         48%~52%

Air pressure             86Kpa~106Kpa (860-1060mbar)

Operating temperature range

The operating temperature range is the range of ambient temperatures at which the capacitor can be operated continuously at rated voltage.

Temperature compensation use:
