GUS-QS0B-03-5621-DB Description

The GUS-QS0B-03-5621-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 5.62KΩ resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of 70°C to 125°C. The network supports a maximum voltage rating of 100V and a total power dissipation of 1W (0.05W per resistor), making it suitable for compact, high-density PCB designs. Its gull-wing termination ensures reliable solder joints in automated assembly processes.
