nominal value of the capacitance measured at θamb = 25 ± 10°C
maximum operating peak voltage of either polarity (non-reversing
type waveform), for which the capacitor has been designed for
continuous operation
value of the maximum operating recurrent voltage for a given hot
spot temperature and an expected lifetime
peak-to-peak alternating component of the unidirectional voltage
capacitor series self-inductance
capacitor series resistance due to galvanic circuit
rms current value @ 100Hz for continuous operation under natural
convection generating 20°C overheating (255Arms maximum for 2
connexions or terminals and 400Arms maximum for 4 connexions
or terminals)
rms current value @ 100Hz for continuous operation under forced
air generating 20°C overheating (255Arms maximum for 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
two units
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
highest temperature obtained inside the case of the capacitor in
thermal equilibrium
