GS4A031272DAT

GS4A031272DAT Description

The GS4A031272DAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 12.7KΩ resistance and an absolute tolerance of ±0.5%, ensuring exceptional accuracy. The network operates within a wide temperature range of -70°C to +125°C, with a low temperature coefficient of ±25ppm/°C, making it ideal for stable performance in fluctuating thermal conditions. Encased in a rectangular ceramic SOIC package, it offers 0.1W power dissipation per resistor (0.4W total) and a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
