GS4A021781GGT Description

The GS4A021781GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 1.78KΩ and a tight tolerance of ±2%. The network operates over a wide temperature range (70°C to 125°C) with a low temperature coefficient of ±50ppm/°C, ensuring stable performance under thermal stress. Encased in a rectangular ceramic SOIC package, it offers excellent thermal and mechanical stability, with a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
