PHE426 is a single metallized film pulse capacitor from EPCOS, polypropylene dielectric, with a rated voltage of 100 to 1000 VDC, a rated capacitance of 63 to 250 nF, a rated loss of 0.001 to 0.0033 ohms, and a rated frequency of 1 kHz to 100 kHz. The working temperature is –55 to +105 °C.
The PHE426 series are single‑metallized film pulse capacitors with a polypropylene dielectric, designed for pulse operation in SMPS, TV, monitor, electrical ballast and other high‑frequency applications that require stable performance. The capacitors feature radial leads, vacuum‑evaporated aluminium electrodes and are encapsulated in a self‑extinguishing material meeting UL 94V‑0.
Technical data include rated voltages up to 1000 VDC/250 VAC, a wide capacitance range, low dissipation factor, high insulation resistance and defined temperature coefficients. Detailed article tables list dimensions, lead spacing, and packaging options for various voltage and capacitance values.
