GQCB021651JDT Description

The GQCB021651JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 23-resistor array features a 1.65KΩ resistance value per resistor with a 5% tolerance and a ±50ppm/°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 with gull-wing SMD termination, it offers excellent thermal and electrical reliability. The device supports a maximum voltage rating of 100V and delivers a total power rating of 1W (0.05W per resistor), making it suitable for compact, high-density PCB designs. Its EU RoHS non-compliant status may restrict use in certain regions, but its thin-film technology provides superior accuracy and low noise compared to thick-film alternatives.

GQCB021651JDT Features

• Precision Thin Film Technology: Delivers low noise and high stability (±50ppm/°C) for sensitive analog/digital circuits.
• Robust Ceramic QSOP Package: Enhances thermal management and mechanical durability in harsh environments.
• High-Density Integration: 23 resistors in a compact 8.66mm × 6.02mm × 1.47mm footprint, ideal for space-constrained designs.
• Wide Operating Range: Rated for 125°C maximum temperature with derated power up to 70°C.
• Automotive-Grade Alternatives: While not PPAP or Automotive qualified, its performance parallels higher-tier industrial components.
• Gull-Wing Termination: Ensures reliable surface-mount soldering with a 0.64mm terminal pitch for automated assembly.

GQCB021651JDT Applications

This resistor network excels in:

• Signal Conditioning Circuits: Precision voltage dividers or pull-up/down networks in ADCs/DACs.
