Overview
The Vishay ERO F1772-515-2000 is an X2-class metalised polyester film capacitor designed for AC power-line interference suppression. With a capacitance rating of 1.5µF and maximum operating voltage of 250VAC, this through-hole suppression capacitor meets international safety standards and is ideal for retrofit and new-build applications in industrial control circuits, switching power supplies, and appliances.
Key Features
- Class X2 rated — approved for direct connection between phase conductors or phase-to-neutral in AC mains circuits
- Polyester dielectric (MKT) — metallised film construction with inherent self-healing properties
- ±10% tolerance — consistent performance across production batches
- High DC withstand voltage (630V) — permits safe use in overvoltage transient conditions
- Radial lead design — standard 27.5mm pitch for PCB mounting and automatic insertion
- UL/CSA approved — meets EN 132400, VDE 0565-1, and international suppression standards
