Product Overview

The CBB21B(R)/MKPH series are box-type metallized polypropylene film capacitors designed for coupling, decoupling, and filtering in electronic equipment, particularly in high-frequency DC pulse applications. These capacitors feature a non-inductive winding structure with a metallized polypropylene film, utilizing tinned copper wire or gold-plated leads. Encased in UL94V-0 flame-retardant plastic shells and epoxy resin, they offer small size, low loss, and good dimensional consistency. They are widely applied in PD fast charging, AHB resonant circuits, and PFC applications.
