DATASHEET Filters FN766X DC Feedthrough Filter IEC/EN 60939 approval Approvals & Compliances Rated currents from 10 to 200 A 2.5 kV pulse test capability Class Y4 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. DC feedthrough filters are designed and approved for 130 VDC/130 Maximum continuous operating voltage 130 VDC (UL, ENEC) VAC 50/60 Hz operation. 130 VAC, 50/60 Hz (UL, ENEC) 650 VDC max. Rated currents 10 to 200 A 60C max. Features and benefits Capacitor class Y4 Very low internal series inductance High potential test voltage 1700 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/130 V (Mil-HB-217F) <200 A: 680,000 hours Anti-twist protection 200 A: 356,000 hours Custom-specific or dual-versions on request Typical applications Power line filter for 48 VDC battery power Increasing system and information security Telecom base stations Switching and cellular equipment Computer servers UPS power supplies Medical equipment Typical electrical schematic2 EMC/EMI Products Schaffner Group Datasheets 10 Jan 2022 Feedthrough selector table Feedthrough Rated current Leakage current* Capacitance** Inductance DC resistance*** Weight 60C 130 VAC/50 Hz C L 10 kHz R 25C A mA nF nH m g FN 7660-10-M3 10 0.98 10 58 1.06 48 FN 7661-10-M3 10 9.8 100 70 1.2 55 FN 7661-16-M4 16 9.8 100 70 0.7 58 FN 7660-32-M4 32 0.98 10 70 0.65 58 FN 7661-32-M4 32 9.8 100 70 0.7 58 FN 7660-63-M6 63 9.8 100 70 0.42 120 FN 7661-63-M6 63 46 470 186 0.47 250 FN 7660-100-M8 100 46 470 124 0.25 280 FN 7661-100-M8 100 98 1000 186 0.28 320 FN 7660-200-M10 200 46 470 124 0.24 410 FN 7661-200-M10 200 460.7 4700 124 0.24 655 * 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 100 A types 200 A types
