GUS-QS8A-02-1802-JB Description

The GUS-QS8A-02-1802-JB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package features 8 isolated 18K Ohm resistors with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a maximum voltage rating of 100V, this network is engineered for reliability in demanding circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density mounting, while its compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
