This document introduces the features and characteristics of the SL1002A series of Littelfuse. The series products have ultra-low insertion loss, surface mountability, 5kA surge capacity, and can be used to meet Telcordia GR1089 and other standards.
The SL1002A Series Gas Discharge Tubes are surface‑mountable, RoHS‑compliant devices designed for broadband, ADSL, XDSL, satellite, CATV and general telecom applications. They feature ultra‑low insertion loss, very low capacitance (≈1.2 pF) and can withstand fast‑rising transients up to 1 kV/µs.
Electrical characteristics include a 5 kA surge rating (8/20 µs pulse), 10/700 6 kV capability, and a 2000 A 2/10 µs surge rating. The devices are specified for operation from –40 °C to +90 °C and are supplied in both surface‑mount (SM) and core (C) packaging formats.
| RoHS compliance | Lead‑free |
|---|---|
| Surge capability | 5 kA (8/20 µs pulse) |
| Capacitance | ≈1.2 pF (typical) |
| Voltage rating | 10/700 6 kV |
The SL1002A series is rated for a 5 kA surge capability using an 8/20 µs pulse as defined by IEC 61000‑4‑5.
The devices have an ultra‑low capacitance, typically 1.2 pF or less.
