GUS-QS0B-03-2702-GC Description

The GUS-QS0B-03-2702-GC from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 20-pin QSOP package integrates 19 resistors, each with a 27K Ohm resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a ±25ppm/°C temperature coefficient, it delivers excellent stability across a wide operating temperature range of 70°C to 125°C, derated for optimal power handling. The network supports a maximum voltage rating of 100V and offers a total power rating of 1W (0.05W per resistor), making it suitable for compact, high-density designs. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering in automated SMT processes.
