EMC Control Products: Newly Developed Low-Profile Clamp Filter Ready for Mass Production

February 16, 2012

TDK-EPC, a group company of the TDK Corporation, has developed the ZCAT-D series of TDK clamp filters. The new low-profile filters are especially suited for EMI suppression by eliminating noise in the power lines of flat-screen TVs, in speaker lines, and similar applications. Mass production is scheduled to begin in April 2012.

TDK clamp filters employ a vertically split cylindrical ferrite core, with the entire filter enclosed in a resin housing, a construction principle unique to TDK products. The ferrite core, which was developed by applying TDK's original materials technology, ensures excellent magnetic characteristics and effective RF noise suppression.

Because conventional products are too thick to fit into the rear case of flat-screen TVs, the new filter has been slimmed down. This was achieved by modifying the sintering method of the material for the ferrite core, allowing it to be made thinner without negatively affecting performance. The result is a 30 percent height reduction compared to conventional TDK products. The temperature range for usage is -25 to +85 °C.


Main applications
  • Noise suppression in the power lines of flat-screen TVs, speaker lines, and similar applications.
Main features and benefits
  • A modified sintering method for ferrite core achieves a component height of up to 30 percent less than existing products.
