GS4A031371FAT Description

The GS4A031371FAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 1.37KΩ and an absolute tolerance of ±1%. The device operates within a wide temperature range of 70°C to 125°C (derated) and offers a low temperature coefficient of ±25ppm/°C, ensuring stable performance under thermal stress. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this network is engineered for reliability in precision circuits. Its gull-wing termination and surface-mount design facilitate easy integration into compact PCB layouts.
