GUS-QS0B-03-6980-GA Description

The GUS-QS0B-03-6980-GA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors with a 698Ω resistance value, offering a tight 2% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 1W total power dissipation (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 and 0.64mm terminal pitch ensure secure PCB mounting, while the compact 8.66mm × 6.02mm × 1.47mm footprint saves board space. The non-automotive, non-PPAP compliant device is supplied in a tube packaging, making it suitable for prototyping and volume production.
