GUS-QS0B-02-2101-BA Description

The GUS-QS0B-02-2101-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 2.1KΩ resistance value and an exceptional 0.1% tolerance, ensuring minimal deviation in critical circuits. With a ±50ppm/°C temperature coefficient, it delivers reliable operation across a wide temperature range (70°C to 125°C). The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital systems. Packaged in a tube for automated assembly, this surface-mount (SMD) component features gull-wing terminals for secure PCB attachment.
