GUS-QS0B-02-3402-DA Description

The GUS-QS0B-02-3402-DA by TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP device integrates 19 resistors, each with a 34KΩ resistance value and an ultra-tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Rated for 1W total power dissipation (0.05W per resistor), it operates across a wide temperature range of -70°C to +125°C, with a low ±50ppm/°C temperature coefficient for stable performance under thermal stress. The gull-wing termination and 100V maximum voltage rating make it suitable for compact, high-reliability designs in industrial and instrumentation systems.
