GUS-QS8A-02-3921-FA Description

The GUS-QS8A-02-3921-FA 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 3.92KΩ resistance, 1% tolerance, and a ±50ppm/°C temperature coefficient. With a 0.75W (3/4W) total power rating and 0.1W (1/10W) per resistor, it operates reliably across a 70°C to 125°C derated power range, with a maximum operating temperature of 125°C. The gull-wing termination and 0.64mm terminal pitch ensure secure PCB mounting, while its compact 4.9mm × 6.02mm × 1.47mm footprint suits space-constrained designs.

GUS-QS8A-02-3921-FA Features

• Precision Thin Film Technology: Delivers stable performance with low noise and high accuracy.
• Isolated Resistors (ISOL): Each of the 8 resistors operates independently, enhancing design flexibility.
• High Power Handling: 0.75W total rating (0.1W per resistor) outperforms similar networks in power density.
• Wide Temperature Range: Stable operation from 70°C to 125°C (derated) with a 100V maximum voltage rating.
• Robust Packaging: QSOP case with gull-wing leads ensures mechanical durability and ease of assembly.
• Non-Automotive/Non-PPAP: Ideal for industrial and commercial applications where PPAP compliance isn’t required.

GUS-QS8A-02-3921-FA Applications
