0.22uf 275V AC Box Capacitor

This 0.22uf 275V AC Box Capacitor is designed with high reliability and long life (12000 hrs) with high ripple current at high frequency and excellent smoothing ability. These capacitors offer a wide range of applications in the field of including high-frequency applications with high current stress such as deflection circuits in televisions and protection circuits in switched-mode power supply (SMPS) and electronic ballasts.

An AC Box capacitor supports an alternative current voltage at a range of 300V. It is designed with polypropylene dielectric with double metalized polyester film as electrodes. The two leads come in parallel with the body of the capacitor. These leads come out at the same ends of the capacitor. Meanwhile, these capacitors are encapsulated in self-extinguishing resin in a rectangular box of plastic material and tinned brass lugs. Moreover, these box capacitors are ideal for high-frequency board applications including IGBT devices.

AC Box capacitors generally exist as polarized, with one lead being positive and therefore the other being negative. Typically these capacitors tend to possess a sign on the positive side to denote which lead is positive. However these electrolytic capacitors also exist as non-polarized, but they’re not as popular because of the polarized variants. And also the high-temperature resistance of polyester material is 185 Fahrenheit degrees.
