GUS-QS8A-01-4751-GB Description

The GUS-QS8A-01-4751-GB from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. This 16-pin QSOP surface-mount device features 4.75KΩ resistance per resistor with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The isolated (ISOL) circuit design allows independent resistor operation, while the 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding environments. Packaged in a compact 4.9mm x 6.02mm x 1.47mm (LxDxH) QSOP case with gull-wing leads, it offers reliable solderability and space efficiency.
