This document introduces PHB metallized polypropylene film capacitors for switching circuits. It is suitable for applications in industrial controls, SMPS, induction heaters, high-end audio, motor speed control, resonant circuits, and high-frequency electronic ballasts. The capacitor features a wide operating temperature range, low dissipation factor, high insulation resistance, high peak current, good dielectric strength, and long life expectancy.
The PHB series from Illinois Capacitor provides metallized polypropylene film capacitors in 2‑, 4‑, and 6‑lead configurations for switching circuits, motor speed control, SMPS, resonant circuits, and high‑frequency applications. They feature low loss, high voltage capability, and robust construction with tinned copper leads and solvent‑resistant plastic housing.
The document lists detailed electrical specifications, physical dimensions, temperature limits, and reliability data for each capacitance and voltage rating, enabling designers to select the appropriate part for their circuits.
