GUS-QS8A-03-4222-CB Description

The GUS-QS8A-03-4222-CB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package features 8 isolated resistors, each with a 42.2KΩ resistance, a tight 0.25% tolerance, and an ultra-stable ±25ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of -55°C to +125°C, derated up to 125°C. The 100V maximum voltage rating and gull-wing termination ensure robust performance in compact PCB layouts. Packaged in a tube, it combines precision, durability, and ease of assembly.
