This new line of surge arresters is comprised of two- and three-electrode ceramic gas tubes that are designed to protect telecomm and datcomm equipment against electrical transients caused by industrial overvoltages, lightning-related surges, and inductive switching or electrostatic discharges. The gas tubes' high isolation resistance and low leakage currents make the the devices suitable for wireless and RF applications. The arrestors are available at breakdown voltages of 75V to 1500V and have high-energy dissipation capabilities as characterized by their 5 to 100 kA ratings. All of the tubes are UL and CE approved and are available for tape-and-reel insertion. Prices range from $0.30 to $0.90 each. Availability is from stock to eight weeks.
