GUS-QS8A-03-2213-FA Description

The GUS-QS8A-03-2213-FA from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a 16-pin QSOP package with gull wing SMD termination, this component offers a 221KΩ resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. Its 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits requiring isolation (denoted by "ISOL" circuit designator). The thin film technology provides superior accuracy and reliability compared to thick-film alternatives.
