EMurata Introduces the World's First CAN FD Class 3-compatible Common Mode Choke Coil

Murata Manufacturing Co., Ltd. has introduced the wire-wound common mode choke coil (CMCC) DLW32SH101XF2, which is the world’s first*1 CMCC to support DCMR*2 Class 3*3, fulfilling the IEC62228-3*4 requirement for use in CAN FD*5 next-generation automotive networks.

In the automotive industry, technologies that control basic automobile behavior are advancing rapidly with the aim of providing safer and more comfortable driving. In keeping with this market demand, faster automotive networks are required for connecting ECUs*6, sensors, and motors, with the result that conventional CAN*7, which transmits data at a rate of up to 1Mbps (megabits per second) is being replaced with the faster CAN FD.

The new product draws on Murata's CMCC design and manufacturing expertise to deliver the high performance and reliability required for CMCCs used in CAN FD networks while realizing a small size thanks to the company’s unique wire-wound structure.
