Original Press Release:

Murata’s Automotive Ethernet Common Mode Choke Coil Withstands Temperatures up to 150 Degrees C

Hoofddorp, Netherlands: Murata has announced the release of the DLW32MH201YK2 common mode choke coil (CMCC) for Automotive Ethernet (100BASE-T1) applications. The choke coil is able to withstand extreme temperatures and is AEC-Q200 compliant.

In recent years, as cars have become equipped with more advanced features, the number of ECUs installed in them has been increasing in order to support the functions of autonomous driving systems such as ADAS. As networks for connecting these ECUs, high-speed interfaces that support the differential signal transmission systems like Automotive Ethernet are becoming more and more common. Along with, and to serve this trend, there is a growing need for components that can be used in high-temperature environments such as engine compartments.

Murata’s DLW32MH201YK2 common mode choke coil has a very wide operating temperature range of -55 to +150 degrees C, which compares very favourably to the -40 to +125 degrees C temperature range of conventional products, allowing it to be used in harsh temperature environments. This improved performance has been achieved by employing metal termination that absorbs the stresses associated with temperature change, as well as by optimizing the combination of Murata's own original materials and product design. Moreover, as the product’s form factor has been kept to a small size of 1210-inch (3.2 x 2.5 mm), ECUs can be installed in a wider range of areas.

AEC-Q200 compliant, the 80V rated choke coil eases the job of the designer as virtually all companies that are designing and producing automotive applications equipment now specify components that are compliant with this standard.

Mass production of the DLW32MH201YK2 common mode choke coil has begun, and Murata will continue to develop products that meet the needs of the market and contribute to enhancing the automotive networks that support autonomous driving.
