High voltage metallized polypropylene film foil capacitor DGCX PPS103J3DA070C3F0ZR for electronic ballast

Product Overview

The CBB81/PPS series high-voltage metallized polypropylene film/foil capacitors (impregnated type) are designed for high-voltage and high-frequency pulse circuits. These capacitors feature a metallized polypropylene film and aluminum foil composite construction with an internal non-inductive series structure. They are suitable for applications such as TV and monitor deflection circuits (S-correction and line flyback waveforms), electronic ballasts, energy-saving lamps, absorbers, and SCR rectifier circuits. Key advantages include low loss, low internal temperature rise, and high dv/dt and overcurrent capabilities.

Technical Specifications

General Electrical Characteristics

Maximum Pulse Rise Slope (dV/dt)

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