Murata introduces 1210-size common mode choke coils for automotive CAN I/F

Murata Manufacturing Co., Ltd., will be commercially producing the DLW32SH_XK series of 1210 inch size (3.2 x 2.5 mm) common mode choke coils capable of withstanding operating temperatures up to 125°C for the on-board control system interface CAN (Controller Area Network). Mass production of this product is scheduled to begin in July.

Automobiles contain multiple electronic control units (ECU), and these ECUs exchange data with each other by means of the differential interface (CAN) for automobile control.

Currently, 1812 inch size (4.5 x 3.2 mm) common mode choke coils, such as the DLW43SH series, are used for CAN.

However, because the shift toward automatic driving is gaining speed and the number of on-board ECUs has been increasing every year, compact products are in demand in the market.

This is why Murata will be commercially producing the DLW32SH_XK series of 1210 inch size (3.2 x 2.5 mm) common mode choke coils based on the winding technology it has cultivated in the common mode choke coil DLW43SH series for CAN/Flex Ray.
