GS4A018450BBT Description

The GS4A018450BBT 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 resistance value of 845Ω and an exceptional ±0.1% absolute tolerance and ±0.1% ratio tolerance. Encased in a robust ceramic SOIC package, it offers superior thermal stability with a ±100ppm/°C temperature coefficient and operates reliably across a wide temperature range of 70°C to 125°C. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, this component is engineered for precision signal conditioning, voltage division, and isolation circuits. Its gull-wing termination and surface-mount design ensure easy integration into compact PCB layouts.
