GUS-QS8A-03-2800-FF Description

The GUS-QS8A-03-2800-FF from TT Electronics/IRC is a high-performance 8-resistor isolated network designed for precision applications in surface-mount circuits. This 280Ω thin-film resistor array offers a tight 1% tolerance and an ultra-stable ±25ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -70°C to +125°C. Packaged in a 16-pin QSOP with gull-wing termination, it features a compact footprint (4.9mm × 6.02mm × 1.47mm) and a 0.64mm terminal pitch, making it ideal for space-constrained PCB designs. With a 0.1W power rating per resistor (0.75W total) and a 100V maximum voltage rating, it balances power handling with precision. The isolated (ISOL) circuit design allows independent resistor operation, enhancing flexibility in circuit configurations.

GUS-QS8A-03-2800-FF Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• High Power Density: 0.75W total power rating in a miniature QSOP package, outperforming standard arrays in thermal management.
• Wide Temperature Range: Operates reliably from -70°C to +125°C (derated power up to 125°C).
• Isolated Resistors: Independent 280Ω resistors enable versatile biasing, termination, or pull-up/down applications.
• Robust Construction: Gull-wing leads ensure secure SMT soldering, while the tube packaging protects during handling.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and instrumentation use where PPAP compliance isn’t required.

GUS-QS8A-03-2800-FF Applications

• Signal Conditioning: Precision voltage dividers or feedback networks in op-amp circuits.
• Termination Arrays: Matched impedance termination for high-speed data lines (e.g., LVDS, USB).
• Medical Electronics: Stable biasing in patient monitoring equipment due to low TCR and high accuracy.
• Test & Measurement: Calibration circuits or sensor interfaces requiring long-term stability.
• Industrial Controls: Isolated resistor networks for PLCs or motor drive systems.

Conclusion of GUS-QS8A-03-2800-FF

The GUS-QS8A-03-2800-FF excels in applications demanding precision, compactness, and thermal resilience. Its thin-film isolation network and QSOP packaging provide a superior alternative to bulky discrete resistors or less stable thick-film arrays. While not RoHS-compliant, it remains a top choice for non-automotive, high-reliability systems where performance outweighs regulatory constraints. Engineers will appreciate its balance of power handling, accuracy, and space efficiency in critical designs.
