GS4B018250CT

GS4B018250CT Description

The GS4B018250CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 7-resistor bussed network features an 825Ω resistance value with an exceptional ±0.25% absolute tolerance, ensuring reliable performance in precision circuits. Encased in an 8-pin narrow SOIC (SOIC-C) package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing terminations for secure surface mounting. The thin-film technology provides stable operation across a wide temperature range (70°C to 125°C), with a ±100ppm/°C temperature coefficient for minimal resistance drift. Rated for 100V maximum voltage and 0.4W total power dissipation, it is ideal for high-density PCB designs requiring tight tolerances and robust thermal performance.
