GUS-QS8B-02-2800-B Description

The GUS-QS8B-02-2800-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 15 resistors, each with a 280Ω resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of 70°C to 125°C. The network supports a maximum voltage rating of 100V and offers a total power rating of 0.75W (3/4W), distributed as 0.05W (1/20W) per resistor, making it ideal for space-constrained designs requiring reliable power dissipation.
