General Technical Information

The following definitions apply to power capacitors according to IEC 61071.

Nominal value of the capacitance at 20 °C and measuring frequency range of 50 to 120 Hz.

Maximum operating peak voltage of either polarity but of a non-reversing type wave form, for which

the capacitor has been designed, for continuous operation.

Peak-to-peak alternating component of the unidirectional voltage.

Peak voltage induced by a switching or any other disturbance of the system which is allowed for a

limited number of times and duration.

- Maximum duration: 50 ms / pulse

- Maximum number of occurrences: 1000 (during load)

Rms rated value of the insulation voltage of capacitive elements and terminals to case or earth. When

it is not specified in the product data sheet, the insulation voltage is at least:

2

V

R

Maximum permissible repetitive rate of voltage rise of the operational voltage.

Maximum rms current for continuous operation.

Maximum peak current Î

Maximum permissible repetitive current amplitude during continuous operation.

follows:

Î

Admissible peak current induced by a switching or any other disturbance of the system which is

allowed for a limited number of times (1000 times) and duration (50 ms / pulse).

Ambient temperature Θ

Θ

Θ

Temperature of the surrounding air, measured at 10 cm distance and 2/3 of the case height of the

capacitor.
