EMC components:World’s smallest common-mode choke for automotive Ethernet
2017-06-20 | ReturnDespite the 50 percent reduction in size, the ACT1210L choke – which is qualified to AEC-Q200 – has an excellent 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 combination of miniaturization with excellent electrical parameters was made possible by TDK's advanced design and winding technology. Due to the special connection technology of the windings, the common-mode chokes are suitable for a wide temperature range from -40 °C to +125 °C. Furthermore, thanks to the fully automated manufacturing process, the new ACT1210L components offer a very high reliability and meet the highest quality requirements.
Typical applications for these Ethernet common-mode chokes are onboard cameras that can be further miniaturized and designed for even higher operating temperatures. In future, TDK will present components for an even wider temperature range in order to further simplify the design of high-speed communication systems for vehicles.
* Status: March 2017 according to studies by TDK
