DL-PL Series

DL□PL□/NFP series


Common Mode Choke Coils(CMCC) reduce the common mode noise that is problematic in differential transmission (examples: USB, HDMI and Mipi), 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).

Noise suppression effects of common mode choke coils in HDMI interfaces
Since HDMI interfaces are high speed, the signal quality will be impaired if regular normal mode filters are used, therefore, these filters cannot be used. Details of examples where noise can be suppressed using suitable common mode choke coils while maintaining the signal quality can be found below.
