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) reduce the common mode noise that is problematic in differential transmission for non automotive applications (examples: USB, HDMI and Mipi), and for automotive applications (examples: CAN/CAN-FD, 100Base-T1, 1000Base-T1, SerDes, A2B🄬), balanced transmission, power supply 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).
