Film capacitors – Power electronic capacitors
MKP PEC DC
Preliminary data
Lowest operating temperature Θmin
Lowest permitted ambient temperature at which a capacitor may be energized.
B2562*
Maximum operating temperature Θmax
Highest permitted capacitor temperature during operation, i.e. temperature at the hottest point of the
case.
Hot-spot temperature Θhs
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 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.
Pmax =
Θhs − ΘA
R th
Self inductance Lself
The sum of all inductive elements which are contained in a capacitor.
Resonance frequency fr
The lowest frequency at which the impedance of the capacitor becomes minimum.
fr =
1
2π ⋅ L self ⋅ CR
Specifications and characteristics
Application:
The MKP DC series is designed for DC-link applications. Some typical examples of DC-Link
applications are as follows: converters, frequency drives, power conversion, uninterruptible power
supplies, transportation, wind power, solar power, power distribution, etc.
