HOT SPOT TEMPERATURE CALCULATION
See Hot Spot Temperature, page 3.
with
where
Due to the design of the capacitor and its technology, the ther-
mal impedance between the terminations and the core
of the capacitor is low, it is necessary to take care that
the capacitor is never overheated by use of wrongly sized con-
nections.
Do not use the capacitor as a heat sink.
Due to the complexity of the IGBT / capacitor thermal
exchanges, we recommend that thermal measurements shall
be made on the different components. We would be pleased
to advise you on specific applications.
