Greentube™ SL1002 Series Gas Plasma Arresters
®
The Broadband Optimized™ SL1002 series has been especially
developed for use in broadband equipment. Unique design fea-
tures 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 recom-
mended.
FEATURES
• RoHS compliant
• Ultra Low Insertion Loss
• Surface mountable
• 5KA surge capability tested with 8/20µS pulse
as defined by IEC 61000-4-5
• 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 2/10µS surge rating
• Meets FCC part 68 10/160µs waveform, 200A test and
10/560µs waveform 100A test.
