KYOCERA AVX releases new multilayer varistors for automotive Ethernet applicationsERT

As an OPEN Alliance member, KYOCERA AVX has extended its AntennaGuard range with the addition of two new MLVs that meet IEEE 1000BASE-T1 and 100BASE-T1 testing requirements, significantly outperform competing diode solutions, and deliver high reliability in space-saving 0402 and 0603 packages.

The new ASPGuard Series MLVs have small, ultralow-profile, surface-mount packages optimized for high-density designs and exhibit high current and energy handling capabilities, bidirectional overvoltage protection, super-fast, sub-nanosecond response times, and multi-strike capabilities. They also provide EMI/RFI attenuation in their off state, which can reduce or even eliminate the need for additional EMC capacitors, and offer lower insertion loss, lower leakage current, and reliability compared to competing diode solutions. In addition, they are qualified to OPEN (One-Pair Ethernet) Alliance standards for automotive Ethernet applications and AEC-Q200.

Ideal applications for the ASPGuard Series include automotive Ethernet networks, IoT devices, industrial automation and control systems, robotics, RF and optical circuits, sensors, high-speed data lines, antennas, radar, Bluetooth devices, and other capacitance-sensitive, high-density applications in the automotive, industrial, and consumer electronics markets.

KYOCERA AVX’s ASPGuard Series MLVs are rated for working voltages extending from 18-70VDC, capacitance values ranging from just 1.5-4.7pF, energy transients spanning 0.02-0.04J, 1-3A of peak current, and operating temperatures as low as -55°C and as high as +150°C. The series also delivers up to 25kV of electrostatic discharge (ESD) protection per IEC 61000-4-2 and meets 48VDC jump start requirements.
