GUS-QS8A-03-4220-FF Description

The GUS-QS8A-03-4220-FF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications in demanding electronic circuits. Encased in a compact 16-pin QSOP package with gull-wing SMD termination, this resistor network offers a 422Ω resistance per element with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a broad temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in high-density PCB designs. The isolated (ISOL) circuit design allows independent resistor operation, making it versatile for complex circuit configurations.
