EMC Components: TDK announces new miniaturized common-mode chokes for automotive CAN-FD

April 6, 2021

TDK Corporation (TSE:6762) announces the development of its new ACT1210D Series common-mode choke for automotive CAN-FD, which will begin mass production in April 2021.

Automotive LANs are roughly categorized into 4 systems such as body, safety, powertrain and multimedia/information and telecommunications. This product supporting CAN and CAN-FD enables a fivefold data transmission speed of 5 Mbps. Currently, CAN is the most widely used standard for body and other systems, keeping a maximum data transmission speed of 1 Mbps.

While meeting the demands of CiA and IEC standards, the ACT1210D Series common-mode choke also boasts a compact low-profile body (3.2 (L) x 2.5 (W) x 2.5 mm (H)) and noise suppression capabilities. Its unique structural design provides signal mode transfer characteristics (Ssd21) that increase communication quality. The manufacturing process involves a highly automated and extremely precise winder and a wire connection method using the laser welding of metal terminals to achieve high reliability.

Over recent years, demand for the handling of high-speed, large-capacity camera footages in ADAS has increased. TDK offers a wide range of automotive communication products and a 1000BASE-T1 Ethernet standard lineup to deliver optimal performance for these applications. Moving forward, TDK will continue catering to customers’ needs by providing comprehensive product services for common-mode chokes for automotive communication.
