GUS-QS8B-03-3902-J Description

The GUS-QS8B-03-3902-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 15 resistors, each with a 39K Ohm resistance and a 5% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of -70°C to +125°C. The network supports a total power rating of 0.75W (3/4W) and 100V maximum voltage, making it suitable for demanding environments. Its gull-wing termination and 0.64mm terminal pitch facilitate seamless SMD assembly, while the compact 4.9mm × 6.02mm × 1.47mm footprint optimizes board space.
