Gas Discharge Tubes SL1011A and SL1411A Series SL1011A and SL1411A Series RoHS Description The SL1011A and SL1411A series provides high levels of protection against fast rising transients in the 100V/µs to 1kV/µs range usually caused by lightning disturbances. The SL1011A and SL1411A series offers low capacitance (< 1.5pf) which provides low insertion loss at high frequencies. SL1011A offers 5kA protection without destruction whereas the SL1411A offer 10kA surge protection without destruction (maximum single surge of 12kA @ 8/20µs).
