SL1011A Series Gas Plasma Arrester
Description
®
The SL1011A 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 series also features ultra low capacitance
(typically 1pF or less) making them ideal for the protection
of high-speed transmission equipment. These devices are
extremely robust and are able to divert a 5,000A pulse
without destruction.
