Vishay DC-Link Film Capacitors for high stability under high humidity

DC-Link capacitors play a vital role in the performance of industrial and automotive power conversion. Equivalent series
resistance (ESR) and capacitance stability are key to ensuring a long lifetime and predictable behavior during the capacitor
service life.
The exposure to harsh environmental conditions of heat and humidity can affect the stability of ESR and capacitance of the
DC-Link capacitor, affecting its performance in power electronics devices such as renewable energy inverters, UPS systems,
automotive on-board chargers, and thermal management systems. Expected environmental conditions are, therefore, a
valuable design input for DC-Link capacitor selection.
Vishay’s MKP1848 DC-Link film capacitor portfolio covers different levels of temperature humidity bias (THB) categories for
different environments:
