SL1011A and SL1411A Series

Gas Discharge Tube (GDT) Products
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).
