GUS-QS8A-03-61R9-DD Description

The GUS-QS8A-03-61R9-DD is a high-precision 8-resistor thin film network from TT Electronics/IRC, designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull-wing terminations, it offers a 61.9 Ω resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±25 ppm/°C temperature coefficient. The device supports a 0.75W (3/4W) total power rating (0.1W per resistor) and operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for precision circuits in harsh environments. Its isolated (ISOL) circuit design ensures minimal crosstalk, while the 100V maximum voltage rating enhances durability in high-voltage applications.
