Greentube™ SL1003 Series Gas Plasma Arresters
®
The SL1003 series has been especially developed for Broadband
equipment. Unique design features offer high levels of perform-
ance on fast rising transients in the domain of 100V/µS to
1KV/µS, which are those most likely from induced Lightning dis-
turbances. 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.
FEATURES
