FN410-3-02

The Schaffner FN410-3-02 is a high-performance two-stage PCB-mounting EMC filter designed for single-phase applications. It is rated for a continuous operating voltage of 250 VAC and a nominal current of 3 A at 40°C. The filter provides high attenuation across a frequency range from DC to 400 Hz. Key electrical characteristics include an inductance of 2 mH (tolerance -30/+50%), Cx capacitance of 33 nF (±20%), and Cy capacitance of 2.2 nF (±20%). The leakage current is typically 373 µA at 230 VAC/50 Hz. The filter is designed for through-hole PCB mounting with PC pin terminations. It operates over a temperature range of -25°C to +100°C and has a flammability rating of UL 94 V-0. The filter is approved to CSA, ENEC, and UR standards, and complies with UL 1283, CSA 22.2 No. 8, and IEC/EN 60939. Typical applications include electrical and electronic equipment, small to medium-sized machines, single-phase power supplies, and test and measurement equipment. The filter weighs 85 g and has an MTBF greater than 675,000 hours at 40°C/230 V.
