GUS-QS0B-02-1621-BB Description

The GUS-QS0B-02-1621-BB is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding applications requiring tight tolerance and stability. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 1.62KΩ resistance value and an exceptional ±0.1% tolerance, ensuring minimal deviation in critical circuits. With a ±50ppm/°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 offers a total power rating of 1W (0.05W per resistor), making it suitable for power-sensitive designs. Its gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration, while the compact 8.66mm × 6.02mm × 1.47mm footprint optimizes space efficiency.
