GS8B031872GT

GS8B031872GT Description

The GS8B031872GT 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 common 18.7KΩ value and a tight ±2% tolerance. Built using 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. With a 0.05W (1/20) power rating per resistor and 0.8W total power dissipation, it supports 100V maximum voltage ratings, making it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal and mechanical durability.
