Eaton CMS Common Mode Inductors, Surface Mount

These surface mount toroidal common-mode inductors offer 300Vdc isolation across three sizes. They provide a wide inductance range from 5.5uH to 1600uH and support currents up to 7.0 Amps. Designed for effective noise attenuation up to 44 dB and operating up to 100 MHz, these inductors meet the UL94V-0 flammability standard and utilize a ferrite core material. They are ideal for applications such as EMI filters, DC-DC brick power supplies, discrete output supplies, and discrete and point-of-use power supplies (PUPS).
