Murata Launches Common Mode Choke Coils with Metal Terminal Structure
Murata has announced the launch and mass production of its DLW32SH_MF series of common-mode choke coils. These components are specifically designed to meet the stringent DCMR Class 3 requirements of the automotive network CAN FD standard, offering robust noise suppression capabilities. A key differentiator is their ability to support a maximum operating temperature of 150°C, making them suitable for demanding automotive environments.
The automotive industry is rapidly advancing towards autonomous driving and advanced driver assistance systems (ADAS), which necessitates a shift from conventional CAN to higher-speed, higher-capacity CAN FD communication. This increase in communication speed, however, makes systems more vulnerable to noise. High-performance noise suppression components are therefore crucial for ensuring the reliability and integrity of these advanced automotive networks.
To address these evolving needs, Murata developed the DLW32SH_MF series. Despite their compact 1210-inch (3.2mm × 2.5mm) size, these common mode choke coils incorporate a metal terminal structure, which significantly enhances their reliability and durability. This design, combined with Murata's proprietary winding and ferrite assembly technologies, positions the series as a superior solution for noise suppression on critical signal lines in modern automotive applications.
