The difference between film capacitor and ceramic capacitor

What is the difference between film capacitors and ceramic capacitors? This article is a brief introduction for the novices. I hope to help you understand these two capacitors more quickly.

1) Difference between dielectric materials: ceramic capacitor dielectric material is ceramic, film capacitor is made of metal foil as electrode, and it is mixed with plastic film such as polyethylene, polypropylene, polystyrene or polycarbonate. It is wound into a cylindrical shape.

2) Different application occasions: Ceramic capacitors have small capacity, high frequency characteristics, and the use temperature can reach several hundred thousand degrees, and the unit price is not high. Generally used in bypass, filtering applications; film capacitors have higher unit price, better stability, and excellent voltage and current resistance, but the capacity is generally not more than 1mF, generally used for voltage reduction and coupling.
