Why do capacitors generate heat?

Capacitors have resistance in their electrodes and dielectrics. This resistance generates heat when AC current like ripple current passes through capacitors. It is very important to select capasitors with low ESR not to generate heat. Ceramic capacitors have lower ESR among capacitors and are best fit for preventing heat. You can find ESR characteristics of our ceramic capacitors in TY-COMPAS.
