GUS-QS8A-03-1502-GB Description

The GUS-QS8A-03-1502-GB 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 (Quarter Small Outline Package) device features 8 isolated 15KΩ resistors with a tight 2% 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 space efficiency in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable soldering in automated SMT processes. Packaged in a tube for secure handling, this non-automotive (PPAP: No) component is ideal for industrial and commercial electronics where precision and reliability are critical.

GUS-QS8A-03-1502-GB Features
