New varistors offer reliable ESD protection in capacitance-sensitive applications

AVX Corporation has released the new Antenna PowerGuard Series varistors, an ultralow capacitance extension of its reliable AntennaGuard range with new voltage, capacitance, and energy ratings. These varistors exhibit high current and energy handling capabilities, low insertion loss, low leakage current, and unsurpassed reliability compared to diode options. These advantages, combined with AEC-Q200 qualification, bidirectional overvoltage protection, EMI/RFI attenuation, fast response times (<1nS), and multi-strike capabilities make the small SMT packaged series ideal for use in RF and optic circuit, sensor, high-speed and data line, antenna, radar, Bluetooth, Ethernet, and other capacitance-sensitive applications across the automotive, industrial, and commercial markets. "Designed to handle higher transients than our proven-reliable AntennaGuard range, the new Antenna PowerGuard Series varistors are ideal for applications with capacitance-sensitive circuits that need to be protected against higher energy," said Jiri Machanicek, product manager at AVX. "The series is also AEC-Q200 qualified, enabling its use in automotive applications."
