The 818071-SF is a three-phase EMC/RFI filter designed for inverter and power drive systems, featuring a compact book-style housing that enables space-saving installation. It operates at a maximum continuous voltage of 3×530/305 VAC with rated currents ranging from 10 to 230 A at 50°C, and supports operating frequencies from DC to 60 Hz. The filter provides standard attenuation performance with a high potential test voltage of 2260 VDC (P?E) for 2 seconds, an MTBF exceeding 200,000 hours, and a short-circuit current rating (SCCR) of 100 kA per UL508. It is designed for pollution degree 3 per IEC 60664-1, operates across a temperature range of -40°C to +100°C with current derating above 50°C, and meets UL 94 V-0 flammability requirements. The 818071-SF is ideal for machinery, converters, and motor drive applications where compliance with Class C2 or C1 EMI limits is required.
