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). **==> picture [259 x 70] intentionally omitted <==** **----- Start of picture text -----**
