GQCB012551GBT

GQCB012551GBT Description

The GQCB012551GBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 2.55KΩ resistance value per resistor 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 excellent thermal stability and durability. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits.

GQCB012551GBT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy for sensitive analog/digital circuits.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical strength in harsh environments.
• Compact QSOP Package (8.66mm x 6.02mm x 1.47mm): Saves board space without compromising performance.
• Wide Operating Range: Reliable operation from 70°C to 125°C with derated power handling.
• Automated Assembly Friendly: Gull-wing leads and 0.64mm terminal pitch ensure compatibility with high-speed SMT processes.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and instrumentation applications where automotive certification isn’t required.

GQCB012551GBT Applications

This resistor network excels in:

• Voltage Division & Bus Termination: The BUS circuit designator optimizes signal integrity in high-speed data lines (e.g., DDR memory, FPGA I/Os).
• Precision Analog Circuits: Suitable for op-amp feedback networks, sensor interfaces, and ADC/DAC reference dividers.
• Power Management Modules: Handles derated power in DC-DC converters or load-sharing circuits.
• Industrial Control Systems: Ceramic construction resists vibration and thermal cycling in PLCs or motor drives.

Conclusion of GQCB012551GBT

The GQCB012551GBT combines precision, compactness, and reliability, making it a superior choice for engineers needing stable resistor networks in space-constrained, high-temperature designs. Its thin-film technology and ceramic QSOP package outperform similar epoxy-encased arrays in thermal and electrical consistency. While not RoHS-compliant, it remains a cost-effective solution for non-consumer applications demanding long-term performance under stress.
