Product Overview

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

Technical Specifications

General Electrical Characteristics

Maximum Pulse Rise Rate (dV/dt)

If the actual working voltage (U) is lower than the rated voltage (UR), the capacitor can operate at a higher dV/dt. The allowable dV/dt value should be multiplied by UR/U.
