Metallized Polypropylene Film Capacitor with Flame Retardant Epoxy Resin Powder DGCX MPP474J2EB070B200ZR

Product Overview

The CBB21/MPP series metallized polypropylene film capacitors are designed for electronic equipment applications. These capacitors feature a non-inductive winding structure with a flame-retardant epoxy resin powder encapsulation. They are suitable for DC blocking, coupling, decoupling, filtering, bypassing, and other high-frequency, DC, AC, and pulse circuits. Key advantages include excellent self-healing properties, low loss, and low internal temperature rise.
