GS4B038251GDT Description

The GS4B038251GDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications. Featuring a ceramic substrate and thin-film technology, it delivers excellent stability with a ±25ppm/°C temperature coefficient and ±2% absolute tolerance. The network operates within a 70°C to 125°C derated power range, with a maximum voltage rating of 100V and 0.4W total power dissipation. Its gull-wing termination and surface-mount design ensure reliable PCB integration, while the SOIC package offers compactness for space-constrained layouts.

GS4B038251GDT Features
