GUS-QS0B-02-4020-DD Description

The GUS-QS0B-02-4020-DD from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 20-pin QSOP package integrates 19 resistors, each with a 402Ω resistance value and an ultra-tight ±0.5% 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 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 provide robust handling of moderate power loads. Its gull-wing termination ensures reliable solderability in automated PCB assembly processes.
