GS8A029091CAT Description

The GS8A029091CAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance under varying thermal conditions. This 16-pin narrow SOIC device features 8 isolated thin-film resistors, each with a 9.09KΩ resistance and an exceptional ±0.25% absolute tolerance (±0.05% ratio tolerance). Its ±50ppm/°C temperature coefficient ensures minimal resistance drift across the 70°C to 125°C operating range, making it ideal for precision analog and digital circuits. Encased in a robust ceramic SOIC package, it offers superior thermal stability and mechanical durability compared to polymer-based alternatives.

GS8A029091CAT Features
