GUS-QS8A-03-4020-JA Description

The GUS-QS8A-03-4020-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 8-resistor isolated network features a 402Ω resistance per element with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of -70°C to +125°C. Housed in a compact 16-pin QSOP (QSOP-16) package, it offers a 0.75W (3/4W) total power rating (0.1W per resistor) and supports 100V maximum voltage, making it suitable for demanding circuit designs. The gull-wing termination enables secure surface-mount (SMD) assembly, while its thin-film technology provides superior accuracy and long-term stability compared to thick-film alternatives.
