DEFINITIONS

capacitance

nominal value of the capacitance measured at

maximum operating peak voltage of either polarity (non-reversing

rated DC voltage

type waveform), for which the capacitor has been designed for

continuous operation

working voltage

value of the maximum operating recurrent voltage for a given hot

spot temperature and an expected lifetime

ripple voltage

peak-to-peak alternating component of the unidirectional voltage

parasitic inductance

capacitor series self-inductance

series resistance

capacitor series resistance due to galvanic circuit

rms current value @ 100Hz for continuous operation under natural

RMS current

Thermal 1

connexions or terminals and 400Arms maximum for 4 connexions

or terminals)

rms current value @ 100Hz for continuous operation under forced

RMS current

Thermal 2

connexions or terminals and 400Arms maximum for 4 connexions

or terminals)

temperature of the cooling air measured at the hottest position of

the capacitor, under steady-state conditions, midway between

NOTE If only one unit is involved, it is the temperature measured

at a point approximately 0.1 m away from the capacitor container and at two-thirds of

the height from its base

hot spot temperature

highest temperature obtained inside the case of the capacitor in

thermal equilibrium
