Antenna PowerGuard varistors protects against ESD in capacitance-sensitive applications
AVX’ Antenna PowerGuard Series varistors are an ultra-low-capacitance extension of its AntennaGuard range with added voltage, capacitance, and energy ratings. Antenna PowerGuard Series varistors exhibit high current and energy handling capabilities, low insertion loss, low leakage current, and high reliability compared to diode options. These advantages, combined with AEC-Q200 qualification, bidirectional overvoltage protection, EMI/RFI attenuation, fast response times (under 1nsec), and multi-strike capabilities suit the small SMT packaged series for use in RF and optical circuit, sensor, high-speed and data line, antenna, radar, Bluetooth, Ethernet, and other capacitance-sensitive applications across the automotive, industrial, and commercial markets.
These Antenna PowerGuard Series varistors are currently available in two case sizes (0402 and 0603), three working voltages (18, 24, and 30 VDC), 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 – 0.04J, and peak current handling capabilities spanning 1 – 3A, and is 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, and are AEC-Q200 qualified.
