GS4B013900JFT Description

The GS4B013900JFT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding electronic circuits. Encased in a narrow SOIC (SOIC-C) ceramic package, this 390Ω thin-film resistor network offers a 5% absolute tolerance and ±100ppm/°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 100V maximum voltage rating, it is engineered for reliability in compact, surface-mount designs. The 8-pin gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while its rectangular ceramic construction enhances thermal and mechanical durability.
