GUS-QS0B-03-2261-B Description

The GUS-QS0B-03-2261-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 2.26KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance 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 compact, high-reliability designs. Packaged in a gull-wing QSOP format, it offers ease of assembly and robust mechanical stability.

GUS-QS0B-03-2261-B Features
