Film vs. Ceramic Capacitor: What''s the Difference?

Film capacitors are constructed with a rolled up film dielectric. The most common type of film capacitor is the polyester or Mylar variety, although other materials such as polycarbonate and PTFE (Teflon) can also be used. The main difference between these types of capacitors is that film capacitors have higher stability than ceramic capacitors.

Capacitor in Electronics

A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
