X & Y Safety Class Film Capacitors

Würth Elektronik X and Y Safety Class Film Capacitors consist of metallized polypropylene film capacitors designed for X1 and Y2 safety-critical interference suppression. These components meet IEC 60384 14 requirements and carry ENEC10 (VDE), cULus, and CQC certifications, ensuring global compliance for EMI filtering applications. The WCAP FTY2 series addresses the growing challenges of modern EMC design, where higher switching frequencies, increased dv/dt, and mains instability demand more robust suppression components. Its high impulse strength and self-healing film technology provide an elevated safety margin for both consumer and industrial power systems.
