GUS-QS8A-03-3300-FA Description

The GUS-QS8A-03-3300-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 surface-mount termination, this device offers a 330Ω 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 QSOP package (4.9mm x 6.02mm x 1.47mm) features a 0.64mm terminal pitch for compact PCB layouts.
