GS4B032742FDT Description

The GS4B032742FDT 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 27.4KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 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 performance.
