What is the Common Mode Noise Filter (CMNF)?

Noise suppression device used for signal integrity enhancement and common mode noise suppression in differential signal system.

The video provides you with a detailed description of the features of the Common mode Noise Filters and explains how to choose the filter fitting to your needs.

Especially in digital data communication, which has become faster in recent years, measures for eliminating common mode noise are essential - the Common mode Noise Filters are used in such applications.

Features

  1. Wide range lineup
    (Small size or Array type) for  common mode noise suppression
  2. Good signal integrity for high bit rate data transmission.
    Wide pass-band for differential signal.
  3. Simple multi-layer structure
    Good durability and mounting reliability
