GQCB015491GAT Description

The GQCB015491GAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 5.49KΩ resistance value with a tight 2% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 24-pin QSOP ceramic package, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) save board space.

GQCB015491GAT Features

• High Precision: Thin-film technology delivers low TCR (±100ppm/°C) and 2% tolerance for reliable signal conditioning.
• Robust Construction: Ceramic case ensures durability and thermal stability in harsh environments.
• Optimized Power Handling: 1W total power dissipation (0.05W per resistor) supports high-density designs.
• Space-Efficient: QSOP package with 0.64mm terminal pitch maximizes PCB real estate.
• Wide Voltage Range: 100V rating accommodates industrial and automotive-grade applications (though not PPAP/automotive-certified).

GQCB015491GAT Applications

Ideal for precision analog and digital circuits, this resistor network excels in:

• Voltage dividers and bus termination in communication hardware.
• Sensor signal conditioning for medical or industrial equipment.
• ADC/DAC reference networks requiring stable resistance values.
• Power supply feedback loops where low TCR is critical.
  Its non-automotive status makes it best suited for commercial and industrial electronics, particularly where miniaturization and reliability are prioritized.

Conclusion of GQCB015491GAT

The GQCB015491GAT stands out for its precision, compactness, and robust ceramic construction, offering superior performance in high-density, temperature-variable environments. While not RoHS-compliant or automotive-grade, its thin-film technology and gull-wing SMD design make it a top choice for industrial control systems, test equipment, and telecom infrastructure. Engineers will appreciate its balance of power handling, tolerance, and footprint efficiency in critical circuit designs.
