GQCB021210JCT Description

The GQCB021210JCT 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 121Ω resistance per element with a 5% tolerance and ±50ppm/°C temperature coefficient, ensuring reliable performance across a 70°C to 125°C operating range. Housed in a 24-pin QSOP ceramic package, it offers 1W total power dissipation (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuit environments. The gull-wing termination and surface-mount design facilitate automated assembly, while the ±0.1mm height tolerance and 6.02mm × 8.66mm footprint ensure compatibility with high-density PCB layouts.

GQCB021210JCT Features

• Advanced Thin-Film Technology: Delivers superior stability, low noise, and tight TCR (±50ppm/°C) for precision applications.
• Robust Ceramic Case: Enhances thermal management and mechanical durability in harsh environments.
• High-Density Integration: 23 resistors in a compact QSOP package save board space versus discrete components.
• Automation-Friendly: Gull-wing leads and standardized QSOP footprint streamline pick-and-place assembly.
• Wide Operating Range: Rated for -55°C to +125°C, with derated power up to 125°C.
• Non-Automotive (PPAP No): Ideal for industrial, telecom, and instrumentation use where automotive compliance isn’t required.

GQCB021210JCT Applications

This resistor network excels in:

• Signal Conditioning: Voltage dividers, pull-up/pull-down networks in ADC/DAC circuits.
• Bus Termination: Matched impedance for high-speed data lines (e.g., SPI, I²C).
• Medical/Test Equipment: Precision measurement systems benefiting from low TCR and minimal drift.
• Power Management: Current sensing and feedback loops in DC-DC converters.
• Aerospace/Defense: Ruggedized electronics where ceramic packaging resists vibration and thermal cycling.

Conclusion of GQCB021210JCT

The GQCB021210JCT stands out for its thin-film accuracy, compact QSOP form factor, and industrial-grade reliability. While not RoHS-compliant, its ceramic construction and wide temperature range make it a robust choice for non-consumer applications. Engineers will appreciate its balance of performance and integration, particularly in space-constrained designs requiring stable, multi-resistor solutions. For cost-sensitive precision networks, this model offers a compelling alternative to higher-tolerance (1%) arrays.
