GS4B031152GT

GS4B031152GT Description

The GS4B031152GT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package. Designed with thin-film technology, it offers a 11.5KΩ resistance per element with a tight ±2% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Encased in a ceramic SOIC-C series housing, this network ensures superior thermal performance, operating reliably from 70°C to 125°C at derated power. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, it combines durability with precision. The gull-wing termination and 1.27mm terminal pitch facilitate easy surface-mount assembly, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) suit space-constrained designs.
