Product Description
Product Overview
The CBB21B/MPB series is a box-type metallized polypropylene film capacitor designed for high-frequency DC and pulse applications. Featuring a non-inductive winding structure, flame-retardant plastic casing, and epoxy resin encapsulation, these capacitors offer low loss and excellent dimensional consistency. They are widely used in electronic equipment for coupling, decoupling, and filtering in switch power supplies and resonant circuits.
