Product Information

CMF series

Features

  • The CMF series has high common mode impedance in small size.
  • The CMF serried is effective for common mode noise suppression in digital equipment which radiation is caused from cables.
  • Suitable for reflow soldering

Applications

  • Coil Master's CMF series is effective in high frequency noise suppression and suitable for suppression of radiation noise in signal cables. The dual winding type common mode choke coil structure enables noise suppression without degrading the signal. CMF can be used as a common mode filter for USB2.0 & IEEE1394.

CMF-4S series

Features

  • High common mode impedance at high frequency effects excellent noise suppression performance.
  • CMF-4S3216 series realizes small size and low profile. 2x1.6x2.0mm.
  • CMF-4S2012 series realizes small size and low profile. 2.0x1.2x1.2mm.


Applications
  • Common mode noise suppression of signal lines in high speed and density digital equipment such as personal computers and peripherals.


CMF-4SHC series

Features

  • Dual winding configuration makes 1 unit suffice for one port.
  • An excellent TPA/TPB impedance balance is ensured due to winding on a single core.
  • Reflow solderable.


CMF-4L4530 Series

Features

  • Easy mounting on pc board
  • L-element circuit ensures excellent attenuation characteristics over a wide frequency range


Applications
  • EMI countermeasures at signal lines of personal computers microcomputer, peripheral devices, etc.
  • Countermeasures against common-mode noise at composite video signals
