TDK Unveils Chip Varistor with Strong Resistance to ESD
This product provides ESD protection to automotive equipment without interfering with high-speed communication between ECUs.
TDK Corporation has launched new chip varistor, AVRH10C101KT4R7YA8, for automotive application Ethernet with strong resistance to ESD.
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 automobiles, 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 high-speed communications required for future automotive equipment, the new product offers higher reliability by achieving strong ESD resistance.
Moving forward, TDK will continue providing customers with flexible support to design their diversified automotive equipment by expanding the product lineup through further downsizing, increased operating voltage, and expansion of capacitance range, etc.
