GUS-QS0B-03-1802-FB Description

The GUS-QS0B-03-1802-FB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 18K Ohm resistance value and a tight 1% tolerance, ensuring reliable performance in precision circuits. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a 70 to 125°C derated power range, making it suitable for environments with fluctuating thermal conditions. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its robustness in high-density PCB designs. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for industrial and commercial electronics.
