GS4B031051JBT Description

The GS4B031051JBT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount (SMD) applications. Encased in a ceramic SOIC-8 package, it offers a 1.05KΩ resistance per element with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is engineered for reliability in demanding circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic substrate enhances thermal and mechanical stability.
