GUS-QS8A-03-9531-FB Description

The GUS-QS8A-03-9531-FB from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP surface-mount device features 8 isolated resistors, each with a 9.53KΩ resistance value and a tight 1% tolerance. With a ±25ppm/°C temperature coefficient, it ensures stable performance across a wide operating range of -55°C to +125°C. The 0.75W (3/4W) total power rating and 0.1W per resistor make it suitable for power-sensitive designs, while its 100V maximum voltage rating enhances reliability in high-voltage circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy PCB integration.

GUS-QS8A-03-9531-FB Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Isolated Resistor Configuration (ISOL): Each of the 8 resistors operates independently, reducing crosstalk.
• Compact QSOP Package: Measures just 4.9mm (L) x 6.02mm (D) x 1.47mm (H), ideal for space-constrained designs.
• Robust Power Handling: 0.75W total dissipation with derating up to 125°C, ensuring reliability under thermal stress.
• Wide Temperature Range: Operates from -55°C to +125°C, suitable for industrial and automotive environments (though not PPAP/automotive-certified).
• High Voltage Tolerance: 100V rating per resistor, making it versatile for signal conditioning and voltage division.
