SMD3216 Gas Discharge Tube 500A 30% 0.3pF 3216 1206 Surface Mount SMD GDT Arrester Device For Circuit Protection
Description of SMD3216 Gas Discharge Tube
The SMD3216 series has been especially designed to meet data transmission protection requirements. The optimized design features a high level of protection against fast rising transients usually caused by lightning disturbances. For use in high frequency data lines, the series offers ultra low capacitances and shows only marginally signal losses up to high frequencies. The devices are extremely reliable and are able to withstand high surge currents without destruction.
