GUS-QS8A-02-2670-CA Description

The GUS-QS8A-02-2670-CA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a 16-pin QSOP package with gull wing termination, this device offers a 267Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W 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 isolated (ISOL) circuit design ensures independent resistor functionality, while the 100V maximum voltage rating enhances versatility in high-voltage circuits. The compact 4.9mm × 6.02mm × 1.47mm footprint and 0.64mm terminal pitch make it ideal for space-constrained PCB designs.
