Murata Manufacturing Co., Ltd. has started mass production of the DLW43MH series of common mode choke coils to support the vehicle’s BroadR-Reach (100 Mbps) Ethernet system. By introducing this new series to complement the series of products supporting CANBUS/FlexRay^*2, Murata contributing to vehicle Ethernet system.

In the automotive market, the trend toward autonomous driving is gaining speed, and on-vehicle cameras are increasingly becoming a standard feature for viewing the area around vehicles. A high-speed differential interface (hereafter “I/F”) capable of sending large amounts of data is required for this. As a result, installation of BroadR-Reach^® (100 Mbps), an on-vehicle version of Ethernet that has a proven track record in the consumer market, is being promoted.

Murata has achieved required characteristics such as mode conversion characteristics by controlling the balance of the electrostatic stray capacitance between wires, based on its expertise in winding technology gained in producing common mode choke coils for CANBUS/FlexRay, the control system I/F used in automobiles. In the future, Murata will be further downsizing products in this area to promptly meet customers’ needs.
