GUS-QS8B-03-1802-J Description

The GUS-QS8B-03-1802-J from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP-packaged device integrates 15 resistors, each with a 18KΩ resistance value and a tight ±5% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of -70°C to +125°C, making it suitable for demanding environments. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating enhance its robustness in circuit designs.
