GQCB024321GT

GQCB024321GT Description

The GQCB024321GT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It integrates 23 resistors in a 4.32K Ohm configuration with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 24-pin QSOP ceramic package, this surface-mount device offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate reliable PCB mounting, while the ceramic case enhances thermal and mechanical durability.

GQCB024321GT Features

• High-Density Integration: 23 resistors in a compact 8.66mm × 6.02mm × 1.47mm QSOP package, ideal for space-constrained designs.
• Precision Performance: ±50ppm/°C TCR and 2% tolerance ensure accuracy in signal conditioning and voltage division.
• Robust Construction: Ceramic substrate provides superior thermal stability and resistance to environmental stress.
• Automated Assembly Compatibility: Gull-wing leads and surface-mount design streamline high-volume manufacturing.
• Wide Operating Range: Rated for -55°C to +125°C, suitable for industrial and automotive-grade applications (though not PPAP-certified).

GQCB024321GT Applications

This resistor network excels in:

• Analog Signal Processing: Precision dividers, DAC/ADC reference circuits.
• Industrial Control Systems: Sensor interfaces, feedback networks in power supplies.
• Communications Equipment: Impedance matching and termination in high-frequency PCBs.
• Test & Measurement Instruments: Calibration networks requiring low drift over temperature.
  Its non-RoHS compliance may limit use in eco-regulated markets but makes it viable for legacy or specialized systems.

Conclusion of GQCB024321GT

The GQCB024321GT stands out for its combination of precision, power handling, and compactness, leveraging thin-film technology for critical circuits. While not automotive-grade, its ceramic construction and tight tolerances make it a reliable choice for industrial, telecom, and instrumentation designs. Engineers should evaluate its non-RoHS status and unconfirmed part status for long-term availability but can rely on its TT Electronics/IRC pedigree for performance-critical applications.
