GUS-QS8A-02-4700-DA Description

The GUS-QS8A-02-4700-DA from TT Electronics/IRC is a high-precision 8-resistor thin film network designed for demanding surface-mount applications. Encased in a compact 16-pin QSOP package with gull wing terminations, it offers a 470Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 0.75W (3/4W) total power (0.1W per resistor), it operates across a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. Its isolated (ISOL) circuit design ensures independent resistor functionality, making it ideal for precision signal conditioning and voltage division.

GUS-QS8A-02-4700-DA Features

• High Precision: Thin film technology delivers ±0.5% tolerance and ±50ppm/°C stability, critical for analog circuits.
• Robust Power Handling: 0.75W total power dissipation (0.1W per resistor) with derating up to 125°C.
• Compact & Durable: QSOP package (4.9mm x 6.02mm x 1.47mm) with 0.64mm pitch, optimized for high-density PCBs.
• Isolated Design: Independent resistors (ISOL) enable flexible circuit configurations without crosstalk.
• Industrial-Grade: Non-automotive (PPAP No) but suited for telecom, test equipment, and industrial controls.
• Non-RoHS: Suitable for legacy or exempted applications requiring leaded components.

GUS-QS8A-02-4700-DA Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and DAC/ADC interfaces.
• Signal Conditioning: Isolation buffers in sensor arrays or data acquisition systems.
• Medical & Test Equipment: High-stability resistance networks for calibration modules.
• Telecom Infrastructure: Line termination and impedance matching in RF/analog front-ends.
• Power Management: Current sensing or bias networks in DC-DC converters.

Conclusion of GUS-QS8A-02-4700-DA

The GUS-QS8A-02-4700-DA excels in applications demanding tight tolerance, thermal stability, and compact footprint. Its isolated thin film resistors and QSOP packaging make it a superior choice over bulkier arrays or less stable thick-film alternatives. While not RoHS-compliant, it remains a reliable solution for legacy or exempted designs requiring high precision in harsh environments. Ideal for engineers prioritizing performance-per-mm² in space-constrained, high-reliability systems.
