GUS-QS8A-03-7872-JA Description

The GUS-QS8A-03-7872-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP package features 8 isolated resistors, each with a 78.7KΩ resistance (5% tolerance) and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component is engineered for reliability in demanding circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the compact dimensions (4.9mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.
