GUS-QS8A-03-4322-JF Description

The GUS-QS8A-03-4322-JF 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 43.2KΩ resistance value and a tight ±5% tolerance. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it delivers reliable performance in compact designs. The ±25ppm/°C temperature coefficient ensures stability across a wide operating range of -70°C to +125°C, making it suitable for demanding environments. Its gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.
