CBB21/MPP Series Metallized Polypropylene Film Capacitors (Impregnated Type)

Product Overview

The CBB21/MPP series capacitors are designed with a metallized polypropylene film, non-inductive winding structure, and feature tinned copper wire or tinned copper-clad steel wire leads. Encapsulated with flame-retardant epoxy resin powder, these capacitors offer excellent self-healing properties, low loss, and minimal internal temperature rise. They are widely used for DC blocking, coupling, decoupling, filtering, bypassing, and other high-frequency, DC, AC, and pulse circuits in electronic equipment.
