GUS-QS8A-03-4320-JB Description

The GUS-QS8A-03-4320-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 8-resistor isolated network features a 432Ω resistance per element with a 5% tolerance and a ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP (Quarter-Small Outline Package) with gull-wing SMD termination, it offers a compact footprint (4.9mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained PCB designs. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is engineered for durability and efficiency in demanding circuits.
