GUS-QS0B-03-8450-DC Description

The GUS-QS0B-03-8450-DC from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 845Ω resistance value and an ultra-tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±25ppm/°C temperature coefficient, it delivers stable performance across a wide temperature range (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 environments. Its gull-wing termination and compact dimensions (8.66mm x 6.02mm x 1.47mm) facilitate seamless integration into densely populated PCBs.
