Maximum operating temperature max

Highest permitted capacitor temperature during operation, i.e. temperature at the hottest point of the case.

Hot-spot temperature hs / Ths

Temperature zone inside of the capacitor at hottest spot.

Tangent of the loss angle of a capacitor tan 

Ratio between the equivalent series resistance and the capacitive reactance of a capacitor at a specified

sinusoidal alternating voltage, frequency and temperature.

Series resistance Rs

The sum of all Ohmic resistances occurring inside the capacitor.

Thermal resistance Rth

The thermal resistance indicates by how many degrees the capacitor temperature at the hot spot rises in relation

to the dissipation losses.

Maximum power loss Pmax

Maximum permissible power dissipation for the capacitor’s operation.
