GS4A021001DT Description

The GS4A021001DT 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 1KΩ resistance and an absolute tolerance of ±0.5%. The network operates within a temperature range of 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 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.
