GUS-QS8A-02-9531-DA Description

The GUS-QS8A-02-9531-DA from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 9.53KΩ resistance value and a tight ±0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating temperature range of 70°C to 125°C, making it suitable for environments with thermal fluctuations. The 0.75W (3/4W) total power rating and 100V maximum voltage rating further enhance its reliability in high-density PCB designs.

GUS-QS8A-02-9531-DA Features

• Precision Thin Film Technology: Offers low noise and high stability for sensitive analog circuits.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained designs.
• Isolated Resistors (ISOL): Each of the 8 resistors is electrically isolated, enabling flexible circuit configurations.
• Robust Power Handling: 0.1W per resistor and 0.75W total power dissipation, superior to standard networks.
• Gull Wing Termination: Ensures reliable solder joints in automated SMT assembly processes.
• Wide Temperature Range: Operates reliably up to 125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
