GUS-QS0B-03-1872-JF Description

The GUS-QS0B-03-1872-JF from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 18.7KΩ resistance value and a tight ±5% tolerance. Operating within a temperature range of 70°C to 125°C (derated power), it delivers stable performance with a low temperature coefficient of ±25ppm/°C, ensuring minimal resistance drift. 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 demanding circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting. Packaged in a tube, this non-automotive, non-PPAP compliant component is ideal for industrial and commercial electronics.
