Fountain Inn, SC. AVX Corp. has released the new Antenna PowerGuard Series varistors, an ultralow-capacitance extension of its AntennaGuard range with new voltage, capacitance, and energy ratings. Antenna PowerGuard Series varistors exhibit high current and energy handling capabilities, low insertion loss, low leakage current, and improved reliability compared with diode options, the company said. These advantages, combined with AEC-Q200 qualification, bidirectional overvoltage protection, EMI/RFI attenuation, fast response times (< 1 ns), and multi-strike capabilities make the small SMT packaged series suitable for use in RF and optic circuit, sensor, high-speed data-line, antenna, radar, Bluetooth, Ethernet, and other capacitance-sensitive applications across the automotive, industrial, and commercial markets.
The new Antenna PowerGuard Series varistors are currently available in two case sizes (0402 and 0603), three working voltages (18, 24, and 30VDC), and three capacitance ratings (1.5, 2, and 3.3 pF). The series features a 25-kV ESD rating, energy handling capabilities spanning 0.02 to 0.04 J, and peak-current handling capabilities spanning 1 to 3 A, and the devices are rated for use in operating temperatures ranging from -55°C to +125°C with no derating. Antenna PowerGuard Series varistors also meet 48-VDC jump start requirements, are AEC-Q200 qualified and RoHS compliant, and offer nickel-barrier, 100% tin (Ni/Sn) terminations. Parts are shipped on 7” or 13” reels, and lead-time for the series is currently 14 weeks.
