GUS-QS8A-03-2702-CB Description

The GUS-QS8A-03-2702-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 8-resistor isolated network features a 27K Ohm resistance per element with an ultra-tight 0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. Housed in a compact 16-pin QSOP package with gull-wing terminations, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for high-reliability circuits. The thin-film technology provides superior accuracy and low noise, while the isolated (ISOL) circuit design enhances signal integrity in multi-channel systems.
