GUS-QS0B-03-4531-BA Description

The GUS-QS0B-03-4531-BA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 19-resistor network features a 4.53KΩ resistance value with an exceptional 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across its operating range of 70°C to 125°C. Packaged in a 20-pin QSOP with gull-wing SMD termination, it offers a compact footprint (8.66mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch, making it ideal for high-density PCB layouts. Rated for 1W total power dissipation (0.05W per resistor) and 100V maximum voltage, it combines reliability with precision in a tube-packaged, surface-mount solution.
