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*1 . Mass production of this product is scheduled to begin in July.
Automobiles contain multiple electronic control units (ECU*2 ), 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.
