Murata introduces 1210-inch common mode choke coils for use with 100Base-T1 2018-04-04

Overview

In February 2018, Murata Manufacturing Co., Ltd. starts mass production of the DLW32MH_XK2 series of common mode choke coils that support 100Base-T1*1 interfaces for automotive applications.

 

Background

In the automotive market, there has been an acceleration of the trend toward automated driving. To achieve this, there has been an increase of electronic device units, an increase in the importance of Lightweight wire harnesses*2 that connect the various units, and growth in the introduction of high-speed differential transmission interfaces in the transmission of not only control system data but also video and audio system data. 
Legislation has led to the advancement of on-board cameras as standard equipment. There is new application of 100Base-T1 Ethernet interfaces used for the transmission of the video data of vehicle cameras used for peripheral detection.

On this occasion, Murata has miniaturized the existing DLW43MH_XK2 series of 1812-inch size (4.5 mm x 3.2 mm) common mode choke coils and has been released them as the DLW32MH_XK2 series of 1210-inch size (3.2 mm x 2.5 mm) common mode choke coils. In the future, we will be contributing to lighter weight wire harnesses and other products.
