GS7B033902CAT

GS7B033902CAT Description

The GS7B033902CAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 14-pin narrow SOIC device features 13 bussed (BUS) thin-film resistors, each with a 39KΩ resistance and an exceptional ±0.25% absolute tolerance (±0.05% ratio tolerance). Its ±25ppm/°C temperature coefficient ensures stability across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. Encased in a rectangular ceramic SOIC package, it offers robust performance with a 0.7W total power rating (0.05W per resistor) and a 100V maximum voltage rating. The gull-wing termination and 1.27mm terminal pitch facilitate easy surface-mount assembly, while its compact dimensions (8.66mm x 5.99mm x 1.45mm) save board space.
