GUS-QS8A-02-3301-CB Description

The GUS-QS8A-02-3301-CB 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 3.3KΩ resistance, offering a tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for precision analog and digital circuits. The gull-wing termination ensures secure PCB mounting, while the compact 4.9mm x 6.02mm footprint and 1.47mm profile optimize space efficiency.
