GUS-QS0B-03-4531-JA Description

The GUS-QS0B-03-4531-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in compact surface-mount assemblies. This 20-pin QSOP package integrates 19 resistors with a 4.53KΩ resistance value, offering a 5% tolerance and a ±25ppm/°C temperature coefficient for stable operation across a wide temperature range (70°C to 125°C). With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it combines reliability with space efficiency. The gull-wing termination ensures secure PCB mounting, while the tube packaging facilitates automated assembly. Its non-automotive and non-PPAP compliance makes it ideal for industrial and commercial electronics.
