GUS-QS8A-02-2102-BA Description

The GUS-QS8A-02-2102-BA is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding surface-mount (SMD) applications. This 16-pin QSOP package integrates 8 isolated resistors, each with a 21KΩ resistance, 0.1% tolerance, and a ±50ppm/°C temperature coefficient, ensuring exceptional stability across a wide temperature range (70°C to 125°C). With a 0.75W (3/4W) total power rating and 0.1W per resistor, it supports robust performance in compact designs. The gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the 100V maximum voltage rating enhances versatility in high-voltage circuits.

GUS-QS8A-02-2102-BA Features

• Precision Thin Film Technology: Delivers low noise, high accuracy (0.1%), and stable performance in fluctuating temperatures.
• Isolated Resistor Network (ISOL): Each of the 8 resistors operates independently, ideal for signal isolation and multi-channel applications.
• Compact QSOP Package: Measures just 4.9mm (L) × 6.02mm (D) × 1.47mm (H), saving board space without sacrificing power handling.
• High Power Density: 0.75W total dissipation and 0.1W per resistor outperform similar networks in power efficiency.
• Wide Operating Range: Functions reliably from -55°C to +125°C, with derated power up to 125°C.
• Automotive-Grade Alternatives: While not PPAP or automotive-certified, its thin-film robustness suits industrial and telecom environments.

GUS-QS8A-02-2102-BA Applications

• Precision Analog Circuits: Voltage dividers, feedback networks, and DAC/ADC interfaces requiring tight tolerance (±0.1%).
• Medical Equipment: Patient monitoring systems where signal integrity and thermal stability are critical.
• Test & Measurement Instruments: Calibration modules and sensor interfaces benefiting from low TCR (±50ppm/°C).
• Industrial Automation: PLCs and motor drives needing isolated resistors for noise immunity.
• Telecom Infrastructure: RF amplifiers and baseband processing with high-voltage (100V) requirements.

Conclusion of GUS-QS8A-02-2102-BA

The GUS-QS8A-02-2102-BA excels in high-precision, space-constrained designs, combining thin-film reliability, isolated resistor topology, and QSOP compactness. Its 0.1% tolerance, low TCR, and 0.75W power rating make it a superior choice over generic arrays for mission-critical analog systems. While not RoHS-compliant, its performance in industrial, medical, and telecom applications justifies its niche dominance. Engineers prioritizing accuracy, thermal resilience, and miniaturization will find this network indispensable.
