DATASHEET Filters FN761X AC Feedthrough Filter IEC/EN 60939 approval Approvals & Compliances Rated currents from 10 to 63 A 5 kV pulse test capability Class Y2 capacitor Feedthrough filters offer a high insertion loss across a broad band of frequencies from a few tens of kHz up to the GHz region. In general, feedthrough filters offer a higher level of EMI suppression than feedthrough capacitors of the same current rating. This is particularly relevant to applications where source impedance is smaller than 50 . Different versions are Technical specifications available offering a wide selection on operating currents and performance levels. AC feedthrough filters are designed and approved for up to 300 VAC Maximum continuous operating voltage 300 VAC, 50/60 Hz (ENEC) 50/60 Hz operation. 250 VAC, 50/60 Hz (UL) 1000 VDC max. Rated currents 10 to 63 A 60C max. Features and benefits Capacitor class Y2 Very low internal series inductance High potential test voltage 3000 VDC for 2 sec Very high self-resonant frequency Insulation resistance (100VDC after 60 sec) <0.33 F, R >15,000 M >0.33 F, >5000 s Self-healing dielectric Temperature range (operation and storage) -40C to +100C (40/100/21) High quality and reliability Flammability corresponding to UL 94 V-2 or better Through-bulkhead mounting MTBF 60C/300 V (Mil-HB-217F) <200 A: >675,000 hours Anti-twist protection 200 A: >494,000 hours Custom-specific or dual-versions on request Operating frequency DC to 60 Hz Typical applications Power line filter for 110/240 VAC power lines Increasing system and information security Power supplies Switching and cellular equipment Computer servers UPS power supplies Medical equipment Shielded rooms Typical electrical schematic2 EMC/EMI Products Schaffner Group Datasheets 27 Sep 2021 Feedthrough selector table Feedthrough Rated current Leakage current* Capacitance** Inductance DC resistance*** Weight 60C 250 VAC/50 Hz C L 10 kHz R 25C A mA nF nH m g FN 7611-10-M3 10 1.89 10 70 1.2 55 FN 7612-10-M3 10 8.86 47 70 1.52 70 FN 7611-16-M4 16 4.15 22 70 0.65 80 FN 7612-16-M4 16 18.85 100 70 0.92 90 FN 7611-32-M4 32 4.15 22 70 0.65 80 FN 7612-32-M4 32 18.85 100 70 0.92 90 FN 7611-63-M6 63 28.3 150 186 0.47 250 FN 7612-63-M6 63 88.6 470 124 0.53 500 * Tolerance +20% ** Tolerance 20% *** Tolerance +15% Typical filter attenuation Full load, 50 system 10 A types 16 A types 32 A types 63 A types
