GUS-QS0B-03-3320-FB Description

The GUS-QS0B-03-3320-FB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP surface-mount device integrates 19 resistors, each with a 332Ω resistance value and a tight 1% tolerance, ensuring reliable signal conditioning and voltage division. With a ±25ppm/°C temperature coefficient, it delivers exceptional stability across a wide operating 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 demanding circuits. Packaged in a gull-wing QSOP case, it offers compact dimensions (8.66mm x 6.02mm x 1.47mm) and a 0.64mm terminal pitch for high-density PCB layouts.
