Terms and characteristics

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

Rated capacitance CN

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

Rated DC voltage VRDC

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.

Ripple voltage Vr

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

Maximum surge voltage Vs

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)

Insulation voltage Vi

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:

Vi = VR

2

Maximum rate of voltage rise (dV/dt)max

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

Maximum current Imax

Maximum rms current for continuous operation.

Maximum peak current Î

Maximum permissible repetitive current amplitude during continuous operation.

Maximum peak current (Î) and maximum rate of voltage rise (dV/dt)max on a capacitor are related as follows:

Î = C · (dV/dt)max

Maximum surge current Î s

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).

Îs = C · (dV/dt)s

Ambient temperature A

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

Lowest operating temperature min

Lowest permitted ambient temperature at which a capacitor may be energized.
