GUS-QS8B-02-2940-D Description

The GUS-QS8B-02-2940-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 294 Ω resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50 ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The network supports a maximum voltage rating of 100V and offers a total power dissipation 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.
