Greentube™ SL1002A Series Gas Plasma Arrester
®
The Broadband Optimized™ SL1002 series has been especially
developed for use in broadband equipment. Unique design
features offer high levels of performance on fast rising transients
in the domain of 100V/µS to 1KV/µS, which are those most likely
from induced Lightning disturbances. These devices have Ultra
low capacitance (typically 1.2pF or less) and present insignificant
signal losses up to 1.5GHz. These devices are extremely robust
and are able to divert a 5000A pulse without destruction. For AC
Power Cross of long duration, overcurrent protection is
recommended.
