POLYESTER CAPACITORS

This reliable dielectric has years of experience in a variety of applications and has earned a reputation for long, reliable life. This rugged dielectric is typically used in applications from -55°C to +85°C. The usage temperature can be extended to +125°C by derating the voltage. Typically, the operating voltage is linearly derated by 50% from 85° through 125°C.

Capacitor Construction:

Construction with this dielectric is typically extended foil in either the film and foil, or metallized constructions. The foil is either aluminum or tin. Film-foil types are used when high peak currents are required or self-healing is perceived as a problem. The metallized types offer vapor deposited metal electrodes and give significant size savings. Self-healing removes a fault or short circuit by vaporizing the electrode in the region of the short and restores the capacitor to useful life, thereby greatly extending the lifetime of the capacitor. Metallized polyester capacitors are among the most reliable of electronic devices.

Encasement:

Polyester dielectric capacitors can be manufactured in a variety of encasements. Typical encasements are wrap and fill, epoxy molded, preformed box, epoxy or durez dipped and metal enclosed.
