GS8A029090CAT Description

The GS8A029090CAT from TT Electronics/IRC is a high-precision 8-resistor isolated network in a 16-pin narrow SOIC package, designed for demanding electronic applications. Featuring a 909Ω resistance value with an exceptional ±0.25% absolute tolerance and ±0.05% ratio tolerance, this thin-film ceramic-based network ensures superior stability and accuracy. Its ±50ppm/°C temperature coefficient and 0.1W power rating per resistor (0.8W total) make it ideal for precision circuits operating in 70°C to 125°C environments. The 100V maximum voltage rating and gull-wing termination further enhance its reliability in surface-mount (SMD) designs.
