Greentube™ SL1024A Series Gas Plasma Arrester
®
The SL1024A series offers high levels of current handling on fast
rising transients created by induced Lightning disturbances.
These devices are extremely robust and are able to divert pulses
of 10,000A. The SL1024A also features ultra low capacitance
(typically 1pf or less) making them ideal for the protection of
high-speed transmission equipment.
FEATURES
• RoHS compliant except ‘RS’ suffix
• Low insertion loss
• Excellent response to fast rising transients.
• Ultra low capacitance.
• 10KA surge capability tested with 8/20µs pulse as defined by
IEC 61000-4-5
• Available with thermal failsafe option (add ‘F’ or ‘S’ suffix to
part number)
