GUS-QS8A-02-4222-JB Description

The GUS-QS8A-02-4222-JB 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 42.2KΩ resistance (5% tolerance) and a ±50ppm/°C temperature coefficient, ensuring stable performance across a 70°C to 125°C derated power range. With a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, it supports robust operation in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the 1.47mm low-profile height suits space-constrained applications.
