TDK further shrinks common-mode chokes for CAN and FlexRay

November 28, 2013 // By Christoph Hammerschmidt
For deployment in both CAN and FlexRay data bus environments, TDK has developed the ACT1210 series of common-mode chokes. With compact dimensions of just 3.2 mm x 2.5 mm x 2.4 mm, the chokes are the world’s smallest, claims TDK - the space it occupies on the PCB is 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 ACT1210 common-mode chokes employ a further improved ferrite and is based on the joint technology competence of TDK and EPCOS in the area of EMC. Thanks to the structural design of the new 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.

Mass production of the components, which are qualified to AEC-Q200, will begin in December 2013.
