GUS-QS8A-03-4420-JF Description

The GUS-QS8A-03-4420-JF from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin QSOP package with gull-wing surface-mount termination, this device offers a 442Ω resistance per resistor with a 5% tolerance and a low ±25ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power and 0.1W per resistor, it operates reliably across a wide temperature range of 70°C to 125°C, with a maximum operating temperature of 125°C. Its compact dimensions (4.9mm length × 6.02mm depth × 1.47mm height) and 0.64mm terminal pitch make it ideal for space-constrained PCB designs.

GUS-QS8A-03-4420-JF Features

• Thin-film technology: Ensures high stability, low noise, and precise resistance matching.
• Isolated circuit design (ISOL): Each resistor operates independently, enhancing flexibility in circuit design.
• Robust power handling: Supports 100V maximum voltage rating and derated power up to 125°C.
• QSOP package: Combines high density with reliable surface-mount (SMD) assembly.
• Non-automotive, non-PPAP: Suitable for industrial and commercial applications where PPAP compliance is not required.
• Tube packaging: Facilitates automated pick-and-place processes.

GUS-QS8A-03-4420-JF Applications

This resistor network excels in:

• Signal conditioning and voltage division in precision analog circuits.
• Feedback networks for op-amps and ADCs/DACs.
• Industrial control systems requiring stable performance under thermal stress.
• Medical electronics where low TCR (±25ppm/°C) minimizes drift.
• Telecommunications equipment leveraging its compact footprint and isolation.

Conclusion of GUS-QS8A-03-4420-JF

The GUS-QS8A-03-4420-JF stands out for its thin-film accuracy, isolated design, and robust power handling in a miniaturized QSOP package. While not RoHS-compliant, its 5% tolerance, low TCR, and 100V rating make it a reliable choice for industrial and precision electronics. Engineers will appreciate its balance of performance, density, and thermal resilience in demanding applications.
