GUS-QS8A-02-3901-GB Description

The GUS-QS8A-02-3901-GB 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 3.9KΩ resistance, 2% tolerance, and a ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C (derated) and up to 125°C maximum. The gull-wing termination and 0.64mm terminal pitch ensure easy PCB integration, while its compact dimensions (4.9mm length × 6.02mm depth × 1.47mm height) make it ideal for space-constrained designs.

GUS-QS8A-02-3901-GB Features

• Thin-Film Technology: Delivers superior stability, low noise, and high precision.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, enhancing design flexibility.
• High Power Handling: 0.75W total (0.1W per resistor) with a 100V maximum voltage rating.
• Robust Construction: QSOP package with gull-wing leads for reliable surface mounting.
• Wide Operating Range: -55°C to +125°C, suitable for industrial and automotive (non-PPAP) environments.
• Low TCR: ±50ppm/°C ensures minimal resistance drift under thermal stress.
