FN7511-100-M8

The Schaffner FN7511-100-M8 is a Y2 class AC feedthrough capacitor designed for high-current power line filtering applications. It offers a capacitance of 0.1 µF with ±20% tolerance and is rated for a maximum continuous operating voltage of 1000 VDC and 250 VAC (UL rating). The component can handle a rated current of 100 A at 60°C and features a very low DC resistance of 0.23 mΩ typical. It meets IEC/EN 60384-14 safety standards and is approved for Y2 applications.

The capacitor is housed in an axial package with M20x1 threaded terminals, enabling through-bulkhead mounting. Its dimensions are 32.00 mm diameter by 113.00 mm length. The operating temperature range spans -40°C to +100°C. Key electrical characteristics include a leakage current of 4.4 mA at 250 VAC/50 Hz, a high potential test voltage of 3000 VDC for 2 seconds, and a minimum MTBF of 1,600,000 hours at 60°C/300 V per Mil-HB-217F.

Typical applications include power line filters for 110/240 VAC systems, UPS power supplies, medical equipment, shielded rooms, and switching or cellular equipment. The self-healing dielectric and very low internal series inductance contribute to high reliability and broad frequency suppression.
