GUS-QS8B-01-4021-D Description

The GUS-QS8B-01-4021-D from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 4.02KΩ resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±100ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -70°C to +125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling of moderate power loads. Its gull-wing termination and compact dimensions (4.9mm x 6.02mm x 1.47mm) facilitate easy integration into high-density PCB designs.
