FN7511-100-M8 – AC Feedthrough Capacitor (EMI filter) – Schaffner

The FN7511-100-M8 is a Schaffner 0.1 µF, 100 A Y2-class AC feedthrough capacitor for high-current EMI/RFI suppression on 250/300 VAC power lines, with through-bulkhead M8-stud mounting.

The FN7511-100-M8 from Schaffner (TE Connectivity) is a high-current AC feedthrough capacitor engineered for effective EMI/RFI suppression on AC power lines. Part of the proven FN751X family, the FN7511-100-M8 delivers 0.1 µF (100 nF) of line-to-ground filtering capacitance in a robust through-bulkhead package rated for continuous currents up to 100 A. Its safety-rated Y2 construction and very low DC resistance make it ideal for feeding clean power through shielded enclosures and EMC barriers where conducted emissions must be tightly controlled.

Built around a cylindrical body (approximately 113 mm long) with an M8 terminal stud and an M20x1 mounting bushing, the FN7511-100-M8 mounts directly into a bulkhead wall to provide a low-impedance ground path right at the point of penetration. Rated to 250 VAC (UL) / 300 VAC (ENEC) and up to 1000 VDC, and approved to EN/IEC 60384-14 with 5 kV pulse test capability and RoHS compliance, it is a dependable choice for demanding industrial, medical, and infrastructure power systems.

Key Features

• Rated capacitance of 0.1 µF (100 nF) with ±20% tolerance for line-to-ground EMI filtering
• High continuous current rating of 100 A at 60°C for power-line feedthrough applications
• Maximum continuous operating voltage of 250 VAC (UL) / 300 VAC (ENEC) at 50/60 Hz; up to 1000 VDC
• Safety-rated Y2 capacitor class for line-to-ground suppression
