GUS-QS8A-03-9530-JA Description

The GUS-QS8A-03-9530-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 953Ω resistance value and a 5% tolerance. With a ±25ppm/°C temperature coefficient, it ensures stable performance across a wide operating range of -70°C to +125°C. The 0.75W (3/4W) total power rating and 0.1W per resistor make it suitable for demanding circuits requiring reliable power dissipation. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration, while the compact 4.9mm x 6.02mm x 1.47mm footprint optimizes board space.
