This document provides technical data for a metallized polypropylene film capacitor. The capacitor features a polypropylene film dielectric and a metal layer deposited by evaporation under vacuum. It has a non-inductive winding and tinned wire leads, as well as a plastic case and thermosetting resin filled for protection. The capacitor is solvent resistant and flame retardant according to UL94 V0. It operates within a temperature range of -40 to +110°C and has a rated voltage of 275Vac (50/60Hz) / 560 Vdc or 300Vac (50/60Hz) / 630 Vdc. The capacitance range is from 0.01µF to 10µF with different tolerance options. The capacitor also has self-healing properties and is used for interference suppression and other applications.
The r.46 X2 Class MKP Series capacitor is a self‑healing, metallized polypropylene film capacitor designed for interference suppression and across‑the‑line applications. It features a metal‑layer deposited by vacuum evaporation, non‑inductive winding, and tinned wire leads, housed in a flame‑retardant plastic case.
Key specifications include a rated voltage of 275 Vac/560 Vdc (300 Vac/630 Vdc for higher range), a capacitance range of 0.01 µF to 10 µF, operating temperature from –40 °C to +110 °C, and a dissipation factor of tgδ 10⁻⁴ at +25 °C. The datasheet also details test methods, performance under damp‑heat and solder‑heat conditions, and packaging options such as ammo‑pack and reel.
