GUS-QS8A-02-1822-BA Description

The GUS-QS8A-02-1822-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 16-pin QSOP surface-mount device integrates 8 isolated resistors, each with a 18.2KΩ resistance and an exceptional 0.1% tolerance. With a ±50ppm/°C temperature coefficient, it ensures minimal resistance drift across a wide operating temperature range of 70°C to 125°C. The network delivers a total power rating of 0.75W (3/4W) and 0.1W (1/10W) per resistor, supporting high-voltage applications up to 100V. Its gull-wing termination and compact 4.9mm x 6.02mm x 1.47mm footprint make it ideal for space-constrained PCB designs.
