X2 Safety Class Film Capacitors

Würth Elektronik X2 Safety Class Film Capacitors are VDE, cULus, and CQC certified film capacitors with a voltage range of 275VAC for the X2 variants and 310VAC for the FTXX and FTXH models. These X2 caps offer self-healing properties and a polypropylene dielectric. They have a capacitance range of 3.3nF to 10µF with ±10% capacitance tolerance. Typical applications for Würth Elektronik X2 Safety Class Film Capacitors are safety, filtering, interference suppression, and power supplies.
