GUS-QS0B-02-3480-DB Description

The GUS-QS0B-02-3480-DB from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP (Quarter Small Outline Package) device integrates 19 resistors, each with a 348Ω resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit designs. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a broad operating temperature range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating further enhance its reliability in high-performance systems. Packaged in a tube for secure handling, this non-automotive, non-PPAP compliant component is ideal for industrial and commercial electronics.
