GUS-QS8A-02-1240-FD Description

The GUS-QS8A-02-1240-FD is a high-performance 8-resistor thin-film network from TT Electronics/IRC, designed for precision applications requiring stable resistance and tight tolerances. Encased in a 16-pin QSOP package with gull-wing surface-mount termination, this 124Ω network offers 1% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it excels in demanding circuits requiring isolation (denoted by "ISOL" circuit designator). Its compact dimensions (4.9mm length × 6.02mm depth × 1.47mm height) make it ideal for space-constrained PCB designs.
