GUS-QS8B-01-2742-B Description

The GUS-QS8B-01-2742-B is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 27.4KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±100ppm/°C temperature coefficient, it maintains stable performance across a wide operating range of -70°C to +125°C. The network supports a maximum voltage rating of 100V and delivers a total power dissipation of 0.75W (3/4W), distributed as 0.05W (1/20W) per resistor. Its gull-wing termination and compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained PCB designs.
