GUS-QS0B-03-2491-G Description

The GUS-QS0B-03-2491-G from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 2.49KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating range of 70°C to 125°C, making it suitable for environments with fluctuating thermal conditions. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in high-density PCB designs. Packaged in a tube for automated assembly, this surface-mount component features gull-wing terminals with a 0.64mm pitch, optimizing space efficiency without compromising durability.
