TDK Corporation reduces size of common-mode choke for automotive Ethernet applications by half
TDK Corporation has announced the ACT1210L common-mode choke for automotive Ethernet applications, such as onboard cameras, which aims to allow further miniaturization of designs and extend operating temperatures to -40 °C to +125 °C. Its dimensions are 3.2 mm x 2.5 mm x 2.5 mm, making it half the size of the existing ACT45L choke. The ACT1210L choke, which is qualified to AEC-Q200, has a Scd21 mode conversion characteristic that is equivalent to that of the existing ACT45L. This key parameter expresses the amplitude relationship between differential and common-mode signal and should be as large as possible. The fully automated manufacturing process gives ACT1210L components high reliability and allows them to meet the highest quality requirements.
Series production of the new common-mode chokes starts in June 2017. Visit www.global.tdk.com for more information.
