GUS-QS8A-02-1072-GA Description

The GUS-QS8A-02-1072-GA from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 16-pin QSOP device features 8 isolated resistors, each with a 10.7KΩ resistance and a tight 2% tolerance, ensuring consistent performance in demanding circuits. With a ±50ppm/°C temperature coefficient, it delivers excellent thermal stability across a wide operating range of -70°C to +125°C. The 0.75W (3/4W) total power rating and 100V maximum voltage rating make it suitable for power-sensitive designs. Its gull-wing termination and surface-mount (SMD) configuration enable easy PCB integration in compact layouts.

GUS-QS8A-02-1072-GA Features

• Thin-Film Technology: Ensures high precision, low noise, and superior stability compared to thick-film alternatives.
• Isolated Resistors (ISOL): Eight independent 10.7KΩ resistors with no shared connections, ideal for signal isolation.
