GUS-QS0B-02-5901-DC Description

The GUS-QS0B-02-5901-DC 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 5.9KΩ resistance and a tight 0.5% tolerance, ensuring exceptional accuracy. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (70°C to 125°C). The network supports a 1W total power rating (0.05W per resistor) and operates at up to 100V, making it suitable for precision analog and digital circuits. Its gull-wing termination and compact dimensions (8.66mm x 6.02mm x 1.47mm) facilitate easy integration into space-constrained designs.
