Suitable for high frequency flame retardant noise suppression sheet (TDK-EPC)

TDK-EPC Corporation (hereinafter referred to as TDK-EPC), a subsidiary of TDK Co., Ltd., has developed a new magnetic suppression film "IRJH3" that has excellent performance in reducing the radiation noise generated by ICs and printed circuit boards of various electronic devices. Mass production began in October this year.

This article refers to the address: http://

The development of this magnetic suppression sheet utilizes the material technology of our company, and combines a soft magnetic material and a polymer material, and uses a magnetic powder prepared with a powder composition and shape. It can reduce the noise in the high frequency band from 10MHz to 3GHz, and has passed the UL94V-0 certification in the United States for the necessary flame resistance of electronic equipment.

The high-frequency noise of various electronic devices that continue to develop in small size and high performance is very serious. The magnetic sheet has a significant effect on noise suppression from a high frequency band of 500 MHz to 2 GHz, which has been increasing in recent years.

It is most suitable for noise countermeasures for various mobile devices including mobile phones and various home appliances including digital cameras and digital video cameras.

the term

  • Soft magnetic material: Magnetic material with large magnetic force and large magnetic permeability
  • UL94V-0: Refers to one of the specifications of the flame resistance index "UL-94" established by Underwriters Laboratories Inc. of the United States.

main application

Noise measures for mobile devices such as mobile phones and various home appliances including digital cameras and digital video cameras.
