GUS-QS0B-03-4530-GG Description

The GUS-QS0B-03-4530-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount (SMD) circuits. This 20-pin QSOP package integrates 19 resistors, each with a 453 Ω resistance value and a tight 2% tolerance, ensuring consistent performance in demanding environments. With a ±25 ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of 70°C to 125°C, making it suitable for thermally challenging designs. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in power-sensitive applications. Packaged in a tube for automated assembly, this gull-wing termination network is RoHS non-compliant but excels in industrial and non-automotive use cases.
