TDK Begins Mass Production of Industry First Automotive Clamp Filter

TDK has developed and began mass production of the industry’s first automotive clamp filter in December. The new filter is called the ZCAT08V-BK, ZCAT12V-BK. TDK developed clamp filters that are suitable for automotive use as an effective noise countermeasure against the effects of electromagnetic noise on the cables that link the various onboard ECUs and units. TDK’s clamp filters have an original structure consisting of a vertically-split cylindrical ferrite core with an integrated resin case for mounting on cables. The ferrite material, a key component of the filter, provides outstanding magnetic characteristics and high-frequency absorption properties achieved through precise control of the fine structure using TDK’s original materials and process technologies.

The resin case and core material have been improved to enhance heat resistant and shock resistance for use in automotive applications. The operating temperature range has been increased from earlier TDK products (-25 C – 85 C) to -40 C – 125 C.
