Common mode noise filter developed by Panasonic

News Hour:

Panasonic Corporation announced today that it has developed the industry-first* “Common mode Noise Filter” corresponding to the high speed data transmission system MIPI(Mobile Industry Processor Interface Alliance) C-PHY of mobile devices such as smart phones, tablets. Samples are available from July, 2016.

For mobile devices such as smart phones and tablets, larger capacity and higher speed of digital data are required in accordance with the high resolution trend of cameras and displays as well as multi-camera trend. In order to achieve high speed transmission, the MIPI C-PHY, which is the new specification of the high speed data transmission system MIPI, has been established and will be released to the market for camera use within 2016.


In the mobile devices represented by smart phone, a large amount of digital data is being transmitted and received between the camera and the display. The common mode noise filter used to remove the generated noises is required correspond to the new specification.

Panasonic has commercialized the industry-first “Common mode Noise Filter” corresponding to MIPI C-PHY using its unique plating fine coil process and ceramic multilayer process.

  1. First in industry, corresponding to high speed, large capacity new trasmission specification MIPI C-PHY
    Corresponding to C-PHY data transmission rate 2.5 Gsps(=5.7Gbps/Trio),approximately 1.5times the conventinoal system.
  2. Unique plating fine coill process and ceramic multilayer process enable compact size Single type dimension : 0.9 X 0.68 X0.40mm typ. Compact size enables reduction of wiring area of high speed data trasmision lines Around 40 % Reduction of mouting area comparing whith conventional system(MIPI D-PHY) in terms of same amout of data trasmission.
  3. Reduction of 1GHz to 5GHz wide band zone common mode noise Wireless receiving performance up of equipped devices.
