Due to the design of the
capacitor and its technology, the thermal 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 incorrect sized
connections.In the case where the series diodes are screwed to thecapacitor, cooling of the diodes must be taken in account.Do not use the capacitor as a heat sink.Due to the complexity of the diode/capacitor thermalexchanges, we recommend that thermal measurements
shall be made on the different components. We would be
pleased to advise you on specific problems.
