TDK Provides Chip Varistors With Strong ESD Resistance for Automotive Ethernet

     TDK Corporation has expanded its product lineup with the introduction of a new chip varistor model AVRH10C101KT4R7YA8, which can be used in automotive Ethernet applications with strong anti-static discharge capability 

     The new product utilizes high-precision lamination technology, optimizes the manufacturing process and process design, achieves a narrow tolerance of 4.7±0.57㎊ within the capacitance range, and has a strong ability to withstand voltage ESD up to 25㎸. In addition, the product provides the ESD protection device performance required by the OPEN Alliance 100BASE-T1 ESD Device Specification Version 2.0 and is compliant with that standard. As a chip varistor for automotive, this product achieves the industry's smallest 1005 (1.0 x 0.5 x 0.5 ㎜) size, supports a maximum circuit voltage of up to 70 V, and features high temperature from -55 ℃ to +150 ℃ range of working temperature.

     Since ADAS (Advanced Driver Assistance System) and even more advanced autonomous driving systems require high-speed and low-latency long-distance communication between ECUs, automotive application Ethernet is used as the long-distance 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 communications required for future automotive equipment, the new product also provides increased reliability by enabling robust ESD resistance.
