TDK Corporation recently announced the expansion of its product lineup with the introduction of a new chip varistor, type AVRH10C101KT4R7YA8, for automotive application Ethernet with strong resistance to ESD. Mass production will begin in March 2022.
Utilizing high-precision multilayer technology and optimizing the manufacturing process and process design, the product implements a tight tolerance of 4.7 ± 0.57 ㎊ in the capacitance range and strong resistance to voltage ESD up to 25 ㎸. Moreover, it delivers the performance required for ESD protection devices by OPEN Alliance 100BASE-T1 ESD Device Specification ver.2.0 and is compliant with this standard. It achieves the industry's smallest size of 1005 (1.0 x 0.5 x 0.5 ㎜) as a chip varistor for automobile, supports a maximum circuit voltage of up to 70 V, and has a high operating temperature range from -55 ℃ to +150 ℃.
As ADAS (advanced driver-assistance systems) and even more advanced autonomous driving systems require high-speed and low-delay telecommunication between ECUs, Ethernet for automotive applications is used as telecommunications infrastructure. This product provides ESD protection to automotive equipment without interfering with high-speed communication between ECUs. In addition to support for high-speed communications required for future automotive equipment, the new product offers higher reliability by achieving strong ESD resistance.
