GS8B026490DCT Description

The GS8B026490DCT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Packaged in a 16-pin narrow SOIC (SOIC-C series), this bussed configuration integrates 15 resistors with a 649Ω resistance value and an exceptional ±0.5% absolute tolerance (±0.25% ratio tolerance). Built using thin-film technology, it delivers stable performance with a low ±50ppm/°C temperature coefficient, ensuring reliability across a wide operating range of -70°C to +125°C. The 0.05W (1/20) power rating per resistor and 100V maximum voltage rating make it suitable for precision circuits. Its ceramic case and gull-wing termination enhance durability and ease of surface-mount (SMD) assembly.
