GQCB021051JDT Description

The GQCB021051JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and compact packaging. This 23-resistor array features a 1.05KΩ resistance per element with a 5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring reliable 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 supports 100V maximum voltage. Its gull-wing termination and surface-mount design make it ideal for automated PCB assembly.

GQCB021051JDT Features

• High-Density Integration: Combines 23 resistors in a compact QSOP ceramic case (8.66mm × 6.02mm × 1.47mm), saving board space.
• Stable Performance: Thin-film technology delivers low noise and excellent stability, with a ±50ppm/°C TCR for minimal drift.
• Robust Construction: Ceramic substrate enhances thermal management and durability in harsh environments.
• Automation-Friendly: Gull-wing leads and 0.64mm pitch ensure compatibility with high-speed SMD placement.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and telecom applications.

GQCB021051JDT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers and feedback networks in instrumentation.
• Digital Systems: Pull-up/pull-down arrays for microcontrollers and FPGAs.
• Power Management: Current sensing and load balancing in DC-DC converters.
• Automotive & Industrial Electronics: Despite lacking PPAP/automotive certification, its 125°C rating suits non-critical automotive subsystems and industrial controls.

Conclusion of GQCB021051JDT

The GQCB021051JDT stands out for its high resistor count, thin-film accuracy, and compact QSOP package, making it a versatile choice for space-constrained, precision circuits. While non-RoHS and unconfirmed status may limit some applications, its thermal stability and power handling are ideal for prototyping and mid-volume production in telecom, industrial, and embedded systems. Engineers should verify compliance for regulated markets but can leverage its cost-effective integration for general-purpose designs.
