GUS-QS8B-03-8660-C Description

The GUS-QS8B-03-8660-C from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors with a 866Ω resistance value, offering a tight 0.25% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.05W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. Its gull-wing termination ensures secure PCB mounting, while the 100V maximum voltage rating makes it suitable for low-to-medium voltage circuits. The compact 4.9mm × 6.02mm × 1.47mm footprint and ±0.1mm dimensional tolerances ensure consistent placement in high-density designs.
