GS4B032872DBT Description

The GS4B032872DBT 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 offers a 28.7KΩ resistance 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.
