GUS-QS8A-02-3241-JB Description

The GUS-QS8A-02-3241-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 8-resistor isolated network features a 3.24KΩ resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -55°C to +125°C. Housed in a 16-pin QSOP package with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) ideal for space-constrained PCB designs. With a derated power range of 70°C to 125°C, it delivers 0.1W per resistor and 0.75W total power dissipation, making it suitable for moderate-power applications.
