Murata Commercializes New Common Mode Choke Coil for In-Vehicle Ethernet Standard 10Base-T1S

Murata Manufacturing has begun mass production of the DLW32MH241MX2, a metal terminal type common mode choke coil in a 1210-inch (3.2 x 2.5mm) package, built to meet the requirements of the 10Base-T1S in-vehicle Ethernet standard defined by the OPEN Alliance industry group.

 

A common mode choke coil filters out electrical noise that appears identically across paired signal wires, helping keep data transmission clean, which matters for Ethernet connections running inside a vehicle where electrical interference is common. The new component specifically meets the Scc21 Class 3 and Cp Class 3 specifications required under the OPEN Alliance's standard for 10Base-T1S, an in-vehicle communication standard that connects Ethernet devices at speeds up to 10 Mbps.

 

This development reflects a broader shift happening in the automotive industry. As vehicles rapidly advance toward what's known as CASE, a term covering four trends reshaping mobility: connected, autonomous, shared and service-based, and electrified, the industry has been unifying its network standards, moving away from CAN, long used in vehicle control systems, toward Ethernet, which has become the standard for in-vehicle information systems. As part of that shift, 10Base-T1S is increasingly being considered as the standard for supporting data transmission up to 10 M...
