GS8B034021JAT Description

The GS8B034021JAT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 16-pin narrow SOIC device features 15 bussed resistors with a 4.02KΩ resistance value and a ±5% absolute tolerance, ensuring reliable signal distribution in complex circuits. Built with thin-film technology, it offers a low ±25ppm/°C temperature coefficient, enhancing stability across a wide operating temperature range of -70°C to +125°C. The SOIC package (9.91mm x 5.99mm x 1.45mm) with gull-wing terminations ensures compatibility with automated surface-mount assembly processes. Rated for 100V maximum voltage and 0.8W total power dissipation, it is ideal for high-density PCB designs requiring consistent performance under thermal stress.
