GS4B021370JDT Description

The GS4B021370JDT from TT Electronics/IRC is a high-reliability ceramic resistor network designed for precision applications in demanding environments. This 7-resistor bussed network features a 137Ω resistance value with an absolute tolerance of ±5% and a ratio tolerance of ±0.5%, ensuring consistent performance in matched-resistor applications. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing termination for secure surface-mount assembly. The thin-film technology delivers excellent stability, with a ±50ppm/°C temperature coefficient and a power rating of 0.4W (0.05W per resistor). Rated for 100V maximum voltage and 125°C maximum operating temperature, it is ideal for high-density PCB designs requiring robust thermal and electrical performance.

GS4B021370JDT Features
