GS8A032872CAT Description

The GS8A032872CAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 16-pin narrow SOIC package, it features 8 isolated thin-film resistors, each with a resistance value of 28.7KΩ and an absolute tolerance of ±0.25%. The device operates over a wide temperature range (70°C to 125°C) with a low temperature coefficient of ±25ppm/°C, ensuring stable performance in varying environmental conditions. With a power rating of 0.1W per resistor (0.8W total) and a maximum voltage rating of 100V, this network is engineered for reliability in precision circuits. Its gull-wing termination and surface-mount design facilitate easy integration into compact PCB layouts.

GS8A032872CAT Features
