GS4A012742BBT Description

The GS4A012742BBT 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 27.4KΩ resistance and an absolute tolerance of ±0.1%, ensuring exceptional accuracy. The network operates within a wide temperature range of 70°C to 125°C (derated) and offers a ±100ppm/°C temperature coefficient, making it suitable for stable performance in varying thermal conditions. Encased in a rectangular ceramic SOIC package, it provides 0.1W power rating per resistor (0.4W total) and supports 100V maximum voltage. Its gull-wing termination and surface-mount design facilitate easy integration into compact PCB layouts.
