GUS-QS8A-03-4701-JA Description

The GUS-QS8A-03-4701-JA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 16-pin QSOP package integrates 8 isolated 4.7KΩ resistors with a 5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it balances power handling and compactness (4.9mm x 6.02mm x 1.47mm). The gull-wing termination and 0.64mm pitch facilitate reliable soldering in automated SMD processes.
