GUS-QS0B-03-2702-G Description

The GUS-QS0B-03-2702-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 27K Ohm 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 temperature range of 70°C to 125°C. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-reliability designs. Packaged in a tube for automated assembly, this surface-mount network features gull-wing terminals with a 0.64mm pitch, optimizing PCB space efficiency.

GUS-QS0B-03-2702-G Features
