GUS-QS8B-02-4302-B Description

The GUS-QS8B-02-4302-B is a high-precision thin-film resistor network manufactured by TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 43KΩ resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range of 70°C to 125°C (derated) and up to 125°C maximum operating temperature. The network supports a maximum voltage rating of 100V and offers a total power rating of 0.75W (3/4W), distributed as 0.05W (1/20W) per resistor. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting in space-constrained designs.
