GUS-QS8B-01-4300-GF Description

The GUS-QS8B-01-4300-GF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors, each with a 430 Ohm resistance value and a tight 2% tolerance, ensuring consistent performance. With a 0.75W (3/4W) total power rating and 0.05W (1/20W) per resistor, it balances power handling with compact surface-mount (SMD) design. The thin-film technology delivers excellent stability, with a ±100ppm/°C temperature coefficient, making it suitable for environments with operating temperatures up to 125°C. Its gull-wing termination ensures reliable solder joints, while the 100V maximum voltage rating enhances durability in high-voltage circuits.
