GUS-QS8A-01-42R2-JF Description

The GUS-QS8A-01-42R2-JF from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a compact 16-pin QSOP (QSOP-16) package, this surface-mount device features 42.2Ω resistance per resistor with a 5% tolerance and a ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, it is engineered for reliability in demanding circuits. The isolated (ISOL) circuit design allows independent resistor operation, while the gull-wing termination ensures secure PCB mounting.
