Downsizing and footprint reduction are constant requirements of the market for all applications or equipment and the relative components. Film capacitors are not an exception and time by time is required to reduce the components dimension maintaining the same rated voltage and performances. Decreasing the volume of the components, one of the consequences is a reduction of the power dissipation by its surfaces and therefore a final increasing of its working temperature.
The paper was presented by Evangelista Boni, KEMET Electronics, Bologna, Italy at the 3rdPCNS 7-10th September 2021, Milano, Italy as paper No.4.1.
Beside the downsizing, the spread of electronic devices in automotive market and the ramp up usage of the new WBG (Wide Band Gap) technologies has definitely increased the working temperature requirement for most of the electronic components.
KEMET has taken the commitment of the market to release new innovative series able to work:
at higher temperature
with a higher reliability at the previous maximum operating temperature
