ORDERING INFORMATION
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
