GUS-QS0B-03-3900-DC Description

The GUS-QS0B-03-3900-DC 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 390Ω 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 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-density PCB designs. Packaged in a tube, it features gull-wing terminations for reliable SMD assembly.
