Gas Discharge Tubes
High Performance Beta Range
The SL1021B series offers high levels of performance on fast ris-
ing transients in the domain of 100V/ S to 1KV/ S, which are
those most likely from induced Lightning disturbances. The
SL1021B series also features ultra low capacitance (typically 1pF
or less) and optimised internal geometry which provides low
insertion loss at high frequencies, so are ideal for the protection
of broadband equipment. These devices are extremely robust
and are able to divert a 20,000Amp pulse without destruction.
