Metallized Polypropylene Film Capacitors For example, consider two of the main purposes of capacitors in electric vehicles: to prevent ripple currents from reaching back to the power source, and to smooth out DC bus voltage variations. Capacitors are also vital in protecting semiconductors – originally thyristors, but now usually IGBTs.

With the continuing supply shortage for multi-layer ceramic capacitors (MLCCs), designers are being forced to consider alternatives. In this article, we will look at the factors to be considered if you’re thinking about using polymer capacitors as a replacement. There has been a supply shortage of MLCCs since the end of 2016 and there are no signs of immediate improvement.

NTC thermistors are temperature-dependent resistors that employ special semiconductor ceramics with a negative temperature coefficient (NTC). They have high resistance at room temperature, and when they are energized, they generate heat by themselves and the resistance falls as their temperature rises.
