GUS-QS0B-03-4701-JD Description

The GUS-QS0B-03-4701-JD from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in surface-mount PCB assemblies. This 20-pin QSOP package integrates 19 resistors, each with a 4.7KΩ resistance value and a 5% tolerance, delivering a total power rating of 1W (0.05W per resistor). The device operates over a wide temperature range of 70°C to 125°C (derated) with a maximum operating temperature of 125°C, ensuring reliability in demanding environments. Its ±25ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for stable, low-drift circuits. The gull-wing termination and 0.64mm terminal pitch facilitate easy soldering and high-density mounting.

GUS-QS0B-03-4701-JD Features

• Thin-Film Technology: Offers superior stability, low noise, and tight TCR performance compared to thick-film alternatives.
• Compact QSOP Package: Measures 8.66mm (L) × 6.02mm (D) × 1.47mm (H), ideal for space-constrained designs.
• High Power Density: 1W total power dissipation across 19 resistors, with derating up to 125°C.
• Automated Assembly Friendly: Gull-wing leads and tube packaging streamline pick-and-place processes.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and consumer electronics where PPAP compliance isn’t required.
• BUS Circuit Designator: Simplifies integration into bus line termination, voltage division, or pull-up/down networks.

GUS-QS0B-03-4701-JD Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor conditioning in test/measurement equipment.
• Digital Systems: Bus termination, pull-up/down resistors for I²C, SPI, or memory interfaces.
• Power Management: Load sharing, current limiting, or bias networks in DC-DC converters.
• Industrial Controls: PLCs, motor drives, and instrumentation requiring stable resistance over temperature.
• Telecom Infrastructure: Line drivers, filters, and impedance matching in high-frequency PCBs.

Conclusion of GUS-QS0B-03-4701-JD

The GUS-QS0B-03-4701-JD excels in applications demanding compact size, thermal stability, and repeatable performance. Its thin-film construction and QSOP packaging provide a competitive edge over bulkier or less precise alternatives, making it a cost-effective solution for mid-tolerance designs. While not RoHS-compliant, it remains a robust choice for industrial and commercial electronics where environmental regulations permit. Engineers will appreciate its balance of power handling, density, and ease of integration in high-reliability systems.
