Maximum operating temperature Θ max
Highest permitted capacitor temperature during operation, i.e. temperature at the hottest point of the case.
Hot-spot temperature Θ hs / T hs
Temperature zone inside of the capacitor at hottest spot.
Tangent of the loss angle of a capacitor tan δ
Ratio between the equivalent series resistance and the capacitive reactance of a capacitor at a specified
sinusoidal alternating voltage, frequency and temperature.
Series resistance R s
The sum of all Ohmic resistances occurring inside the capacitor.
ESR
ESR (Equivalent Series Resistance) representing entire active power in capacitor.

Thermal resistance R th
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 P max
Maximum permissible power dissipation for the capacitor’s operation.
P max =
