Leading-Edge AVX Technology in Film Capacitors
Written By: Masato Nishikiori
Abstract:
With the advent of plastics in the middle of the 20th century, the film capacitor was introduced as a technological leap over traditional paper-based designs. Film capacitors use a thin plastic film as the dielectric that separates multiple metal electrodes. The electrodes are either deposited directly on the film (metallization) or are built from separate metal foils. The plastic metal sandwich is wound on a bobbin, and a terminal contact layer is deposited to connect all of the individual capacitor layers in parallel effectively.
