GreentubeTM SL1003 Series Gas Plasma Arresters
High Performance Beta Range
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/
S to
1KV/
S, 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
RoHS
compliant
Low insertion loss
Surface mountable
5KA surge capability tested with 8/20
S pulse as defined by
IEC 61000-4-5
GHz working frequency.
Excellent response to fast rising transients.
Can be used to meet Telcordia GR1089 without
series resistance
10/700 6KV capability, as per ITUT k.21, enhanced test level
2000 Amp 2/10
S surge rating
Applications:
Broadband equipment.
ADSL equipment.
XDSL equipment.
Satellite and CATV equipment.
General telecom equipment.
