GS4A028660BBT Description

The GS4A028660BBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stability. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 866Ω and an absolute tolerance of ±0.1%, ensuring exceptional accuracy. The network operates over a wide temperature range of 70°C to 125°C with a ±50ppm/°C temperature coefficient, making it suitable for environments with thermal fluctuations. Encased in a rectangular ceramic SOIC package, it offers 0.1W (1/10) power rating per resistor (0.4W total) and a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration.
