GUS-QS8A-02-8870-GG Description

The GUS-QS8A-02-8870-GG from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable operation. This 8-resistor isolated network features a 887 Ω resistance per element with a tight 2% tolerance and a low ±50 ppm/°C temperature coefficient, ensuring minimal drift across its 70°C to 125°C derated power range. Encased in a 16-pin QSOP (QSOP-16) package, it offers a compact 4.9 mm × 6.02 mm footprint with a 1.47 mm profile, making it ideal for space-constrained surface-mount (SMD) designs. Rated for 0.75W total power (0.1W per resistor) and 100V maximum voltage, it combines durability with precision in demanding environments.

GUS-QS8A-02-8870-GG Features

• Thin-Film Technology: Delivers superior stability, low noise, and high accuracy compared to thick-film alternatives.
• Isolated Circuit Design (ISOL): Each resistor operates independently, enhancing flexibility in circuit design.
• High Power Density: 0.75W total power rating (3/4W) in a miniature QSOP package optimizes thermal management.
• Wide Temperature Range: Operates reliably from -55°C to +125°C, with derated performance up to 125°C.
• Gull Wing Termination: Ensures robust solder joints and compatibility with automated PCB assembly processes.
• Non-Automotive/Non-PPAP: Suitable for industrial, telecom, and instrumentation applications where automotive compliance isn’t required.

GUS-QS8A-02-8870-GG Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring stable resistance values.
• Signal Conditioning: ADC/DAC reference circuits, where low TCR (±50ppm/°C) minimizes error over temperature.
• Portable Electronics: Space-sensitive devices like medical monitors or handheld test equipment benefit from its compact QSOP-16 package.
• Industrial Controls: PLCs, motor drives, and power supplies leveraging its 100V rating and isolation.

Conclusion of GUS-QS8A-02-8870-GG

The GUS-QS8A-02-8870-GG stands out for its thin-film precision, isolated design, and high power-handling capability in a small form factor. While not RoHS-compliant, its 2% tolerance, low TCR, and 0.75W rating make it a robust choice for industrial and telecom applications demanding reliability under thermal stress. Engineers will appreciate its balance of performance and miniaturization, particularly in analog signal chains and power-sensitive designs.
