GUS-QS8A-03-6981-DB Description

The GUS-QS8A-03-6981-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 6.98KΩ resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C. The device supports a maximum voltage rating of 100V and offers a total power rating of 0.75W (3/4W), with 0.1W (1/10W) per resistor, making it suitable for power-sensitive designs. Its gull-wing termination and compact dimensions (4.9mm x 6.02mm x 1.47mm) facilitate easy integration into high-density PCB layouts.
