GS4B031372DBT Description

The GS4B031372DBT from TT Electronics/IRC is a high-precision 7-resistor thin-film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it features a 13.7KΩ resistance value per resistor with an ultra-tight 0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB mounting, while the ceramic substrate enhances thermal performance.
