GreentubeTM SL1003 Series Gas Plasma Arresters
(R)
The SL1003 series has been especially developed for Broadband equipment. Unique design features offer high levels of performance on fast rising transients in the domain of 100V/S to 1KV/S, 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.
FEATURES
* RoHS compliant * Low insertion loss * Surface mountable * 5KA surge capability tested with 8/20S 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 2/10S surge rating
Applications:
* Broadband equipment. * ADSL equipment. * XDSL equipment. * Satellite and CATV equipment. * General telecom equipment.
