Product Description
Product Overview
The CBB21B(R)/MKPH series are box-type metallized polypropylene film capacitors designed for high-frequency DC pulse applications. Featuring a non-inductive winding structure and encapsulated in a flame-retardant plastic case with epoxy resin, these capacitors offer small size, low loss, and excellent dimensional consistency. They are widely used in switching power supplies for DC coupling, decoupling, filtering, and bypass applications, particularly in high-frequency and PFC circuits.
