The 800667-SF is a current-compensated common-mode choke from the Schaffner RD series designed to attenuate common-mode and asymmetric interference signals in AC power lines. It operates at rated currents from 6 to 64 A with a maximum continuous operating voltage of 600 VAC or 850 VDC, supporting frequencies from DC to 400 Hz. The choke features dual, triple, or quad-choke configurations with high potential test voltages of 2500 V winding-to-winding and 4000 VAC winding-to-housing, ensuring robust electrical isolation and safety. With an operating temperature range of -25°C to +110°C and UL 94 V-0 flammability rating, this component is ideal for industrial power supplies, motor drives, and renewable energy systems requiring reliable EMI suppression and compliance with electromagnetic compatibility standards.
