GS7B031802GT

GS7B031802GT Description

The GS7B031802GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. Housed in a 14-pin narrow SOIC package, this bussed network integrates 13 resistors, each with a 18KΩ resistance and a tight ±2% tolerance. Built with thin-film technology, it delivers exceptional stability with a low ±25ppm/°C temperature coefficient, ensuring reliable performance across a -70°C to +125°C operating range. The SOIC-C series construction features a ceramic case for superior thermal management, with a 0.7W total power rating (0.05W per resistor) and 100V maximum voltage rating. Its gull-wing termination and surface-mount design facilitate automated assembly, while the tube packaging ensures handling efficiency.
