GS7B028661CCT Description

The GS7B028661CCT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 14-pin narrow SOIC package, this bussed (BUS) network integrates 13 thin-film resistors, each with a 0.05W (1/20) power rating and a 0.25% absolute tolerance. The device offers a tight temperature coefficient of ±50ppm/°C, ensuring stable performance across a wide operating range of -70°C to +125°C. With a total power rating of 0.7W, 8.66KΩ resistance value, and 100V maximum voltage rating, it is engineered for reliability in precision circuits. The SOIC-C series construction features gull-wing terminations for robust surface-mount (SMD) assembly, while its ceramic case enhances thermal and mechanical durability.
