TDK provides a chip varistor with strong anti-static discharge capability for automotive Ethernet applications

     TDK has expanded its product portfolio and introduced a new type of patch varistor, AVRH10C101KT4R7YA8, which can be used in automobile application Ethernet and has strong anti-static discharge capability. It has a compact structure, low capacitance, small tolerance, and reliable ESD protection (IEC61000-4-2) up to 25 ㎸, which also conforms to OPEN Alliance 100BASE-T1 ESD device specification version 2.0, with a working temperature up to 150 ℃

     The new products use high-precision lamination technology to optimize the manufacturing process and process design, achieve a narrow tolerance of 4.7 ± 0.57 ㎊ within the capacitance range, and have a strong ability to resist voltage ESD up to 25 ㎸. In addition, the product also provides the ESD protection equipment performance required by OPEN Alliance 100BASE-T1 ESD Device Specification Version 2.0 and complies with this standard. As a chip varistor for automobiles, this product achieves the smallest 1005 (1.0 x 0.5 x 0.5 ㎜) size in the industry, supports the maximum circuit voltage up to 70 V, and has a high operating temperature range from - 55 ℃ to+150 ℃.

     Since ADAS (Advanced Driving Assistance System) and even more advanced auto drive system require high-speed and low delay remote communication between ECUs, the automobile application Ethernet is used as the remote communication infrastructure. This product provides ESD protection for automotive equipment without interfering with high-speed communication between ECUs. In addition to supporting the high-speed communication required by future automotive equipment, this new product also provides higher reliability by realizing strong anti-static discharge capability.
