GUS-QS8A-02-45R3-JF Description

The GUS-QS8A-02-45R3-JF 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 16-pin QSOP (Quarter-Small Outline Package) device features 8 isolated resistors, each with a 45.3 Ω resistance (±5% tolerance) and a ±50 ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports moderate power dissipation while maintaining accuracy. The gull-wing termination and surface-mount design facilitate easy PCB integration, making it ideal for automated assembly processes. Its compact dimensions (4.9mm x 6.02mm x 1.47mm) and 100V maximum voltage rating further enhance its versatility in space-constrained designs.
