Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. …

Capacitors Cooling Explained
Capacitors are rated for ripple current and exceeding the ripple current rating will increase internal heating, limit the overall reliability of the device and reduce the capacitor''s lifetime. High ripple current and high temperature of the environment in which the capacitor operates causes heating due to power dissipation.
