GUS-QS8A-03-4420-CB Description

The GUS-QS8A-03-4420-CB from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull wing terminals, it offers a 442Ω resistance per resistor with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a wide temperature range (-70°C to +125°C), making it suitable for harsh environments. The isolated (ISOL) circuit design ensures independent resistor functionality, while its 100V maximum voltage rating and thin film technology deliver stable performance in precision circuits.
