GUS-QS8A-03-3002-CA Description

The GUS-QS8A-03-3002-CA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 30K Ohm resistance and an ultra-tight 0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C derated, 125°C max). The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for high-reliability environments. Its gull-wing termination and 0.64mm terminal pitch facilitate robust PCB mounting.
