GUS-QS8A-03-78R7-DD Description

The GUS-QS8A-03-78R7-DD is a high-precision, thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 78.7 Ω resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable performance in compact designs. The device operates over a wide temperature range of -70°C to +125°C, supported by a low ±25ppm/°C temperature coefficient, minimizing drift in harsh environments. Its gull-wing termination and 0.64mm terminal pitch facilitate robust PCB mounting, while the 1.47mm profile suits space-constrained applications.
