GUS-QS0B-03-1622-BA Description

The GUS-QS0B-03-1622-BA from 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 16.2KΩ resistance value and an ultra-tight 0.1% 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 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. Packaged in a gull-wing SMD format, it offers reliable solderability and mechanical stability for automated assembly processes.
