EMI Suppression Filters(EMC and Noise Suppression)

Outline of EMI Suppression Filters (EMC and Noise Suppression)Common Mode Choke Coils/Common Mode Noise Filters

DL□/PL□/NFG/NFP series

Common mode choke coils (CMCC) are filters that reduce common mode noise that is problematic in differential transmission lines (non-automotive use: USB, HDMI, Mipi, etc.; automotive use: CAN, CAN-FD, 100Base-T1, 1000Base-T1, SerDes, A²B^®, etc.), power lines, and audio lines.
They are ideal for suppressing common mode noise with frequencies ranging from several megahertz to several hundred megahertz with no adverse effect on the signals (upper cut-off frequency).
