GQCB024751GT

GQCB024751GT Description

The GQCB024751GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP (Quarter Small Outline Package) device integrates 23 resistors with a 4.75KΩ resistance value and a tight 2% tolerance, ensuring consistent performance in demanding circuits. Encased in a ceramic package, it offers excellent thermal stability and durability, with a maximum operating temperature of 125°C and a ±50ppm/°C temperature coefficient. The 1W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for high-reliability designs. Its gull-wing termination and surface-mount (SMD) configuration facilitate easy PCB integration.

GQCB024751GT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical strength in harsh environments.
• BUS Circuit Designator: Optimized for bus line termination, voltage division, and pull-up/down applications.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Compact QSOP Package: Saves board space with 8.66mm (L) × 6.02mm (D) × 1.47mm (H) dimensions and 0.64mm terminal pitch.
• Non-Automotive Grade: Ideal for industrial, telecom, and instrumentation use where PPAP compliance is not required.

GQCB024751GT Applications

This resistor network excels in:

• Signal Conditioning: Precision voltage dividers and feedback networks in op-amp circuits.
• Bus Termination: Impedance matching for high-speed data lines (e.g., SPI, I²C).
• Embedded Systems: Pull-up/down resistor arrays for microcontrollers and FPGAs.
• Test & Measurement Equipment: Stable reference resistors in calibration modules.
• Power Management: Current-limiting networks in low-power DC/DC converters.

Conclusion of GQCB024751GT

The GQCB024751GT stands out for its thin-film accuracy, ceramic ruggedness, and compact QSOP footprint, making it a superior choice over thicker-film or plastic-cased alternatives. While not RoHS-compliant, its high-temperature endurance and low TCR (±50ppm/°C) cater to specialized industrial and telecom applications where reliability trumps regulatory constraints. Engineers will appreciate its balance of power handling, precision, and space efficiency in dense PCB layouts.
