GUS-QS8B-03-4530-JG Description

The GUS-QS8B-03-4530-JG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 453Ω resistance value and a tight ±5% tolerance, ensuring reliable signal conditioning and voltage division. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it delivers robust performance in compact surface-mount designs. The ±25ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments with thermal fluctuations. Its gull-wing termination ensures secure PCB mounting, while the 100V maximum voltage rating enhances durability in high-voltage applications.
