GS7B031802CBT Description

The GS7B031802CBT 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) configuration integrates 13 thin-film resistors, each with a 18KΩ resistance and an exceptional ±0.25% absolute tolerance. The device operates over a wide temperature range of 70°C to 125°C with a ±25ppm/°C temperature coefficient, ensuring stability in fluctuating environments. With a 0.7W total power rating (0.05W per resistor) and 100V maximum voltage rating, it combines robustness with precision. The SOIC-C series construction features gull-wing terminations for reliable surface-mount (SMD) assembly, while its ceramic case enhances thermal and mechanical durability.
