Compact Common-Mode Chokes For CAN, FlexRay

Compact Common-Mode Chokes For CAN, FlexRay

The ACT1210 series of common-mode chokes from TDK Corporation are for both CAN and FlexRay bus systems. With their compact dimensions of just 3.2 mm x 2.5 mm x 2.4 mm, the chokes are reportedly the world's smallest. Their footprint is approximately 45 percent smaller than that of existing components, while their volume has been more than cut in half. Rated for a wide operating temperature range from -55 °C to +150 °C, the ACT1210 series offers high heat resistance and reliability, making it suitable for use under severe conditions such as those encountered in the engine compartment of a vehicle. 

The common-mode chokes, which employs a further improved ferrite, is based on the joint technology competence of TDK and EPCOS in the area of EMC. Thanks to the unique structural design of the series, the components are manufactured using a high-precision autowinding process, which contributes to their high stability and reliability and at the same time ensures their consistent quality.

The series joins the existing ACT45B series for CAN, the ACT45R series for FlexRay, and the new ACT45L series for automotive Ethernet, resulting in a highly versatile lineup of high-performance common-mode chokes for EMC in automotive bus systems.
