EMC filters (electromagnetic compatibility filters) suppress conducted EMI on power supply lines — meeting CISPR, FCC, and EN 55011/55022 conducted emissions limits in power supplies, motor drives, industrial equipment, medical devices, and telecommunications infrastructure. Our EMC filter inventory covers IEC inlet filters (power entry modules with built-in filter), PCB-mount filters, feedthrough filters, and standalone power line filters from Schaffner (FN series), TRV Components (TN/TNV series), Alps Alpine (FSL series), Corcom (RFI series), and TDK-Lambda — with current ratings from 1A to 50A, voltage ratings from 125V to 250V AC, and common-mode and differential-mode attenuation from 10kHz to 30MHz.
High-current (20–50A) IEC inlet EMC filters and medical-grade (MELF) filters meeting IEC 60601-1 are frequently on long lead times. Welllinkchips stocks a range of standard and hard-to-find EMC filter configurations, including obsolete and discontinued types for legacy industrial equipment and medical device repair.
