EMC Solution Components, Common Mode Filters for Automotive Ethernet ACT1210L Series Development and Mass Production

• Volume is reduced by approximately 50% over previous product ACT45L series

• Achieve high common mode conversion characteristics Scd21

• Operating temperature range -40 ~ +125°C

• Fully automated production line ensures high reliability and high quality

• Complies with AEC-Q200

TDK Co., Ltd. (President: Shihei Seiki) has developed the industry's smallest* ACT1210L series common-mode filter for automotive Ethernet (size: L3.2×W2.5×T2.4mm).

At present, common-mode filters for automotive Ethernet have ACT45L series (outline dimensions: L4.5×W3.2×T2.8mm) product lines. In recent years, on-vehicle cameras have been increasingly miniaturized, and miniaturization has been demanded on the basis of high-density assembly while also meeting requirements for high heat resistance.

This product uses the company's unique structural design and coil manufacturing process, even if the miniaturized design, can also ensure the same common mode conversion characteristics Scd21 with ACT45L. The so-called common-mode conversion characteristic Scd2 1 High-level means that the differential-mode signal is not converted to common mode and still has good characteristics as a common-mode filter. In addition, a temperature range of -40 to +125°C and high heat resistance are achieved by using metal terminals. In addition, through a fully automated manufacturing process, high reliability and high quality manufacturing are realized.

In the future, we will further expand our product lineup by expanding the operating temperature range and corresponding high-speed communications to meet a wide range of vehicle-mounted device designs.

Terminology

• Common-mode conversion characteristics Scd21: Indicates the amount of conversion from differential to common mode. The larger the negative number, the smaller the amount of common mode conversion, which suppresses the generation of common mode noise.

main application

• Car Ethernet System

Main features and advantages

• Using unique structural design and coil technology in miniaturization to achieve the same common mode conversion characteristics as existing products Scd21

• Small size and space saving

• The use temperature range of -40 ~ +125°C is achieved through the use of metal terminals

• Stable quality through a fully automated production line
