GQCB0251R0JDT Description

The GQCB0251R0JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 23-resistor array features a 51Ω resistance value with a 5% tolerance and a ±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, it offers a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) save board space.

GQCB0251R0JDT Features

• Thin-film technology: Delivers superior accuracy and low noise compared to thick-film alternatives.
• Ceramic case: Enhances thermal stability and durability in harsh environments.
• BUS circuit designator: Optimized for bus line termination and pull-up/pull-down applications.
• High power density: 1W total dissipation in a compact QSOP package.
• Wide operating range: Reliable performance from -55°C to +125°C (derated above 70°C).
• RoHS non-compliant: Suitable for legacy or specialized industrial systems.

GQCB0251R0JDT Applications

Ideal for:

• Bus termination networks in digital communication systems (e.g., CAN, I2C).
• Voltage dividers and pull-up/down circuits in microcontrollers and FPGAs.
• Signal conditioning in automotive infotainment (though not PPAP/automotive-qualified).
• Medical and industrial control systems requiring stable, low-drift resistance.
• High-density PCBs where space-saving SMD components are critical.

Conclusion of GQCB0251R0JDT

The GQCB0251R0JDT excels in precision analog and digital circuits, combining thin-film reliability, compact packaging, and robust power handling. Its 5% tolerance and ±50ppm/°C TCR make it a cost-effective choice for non-automotive applications needing consistent performance. While not RoHS-compliant, its ceramic construction and QSOP gull-wing design ensure longevity in industrial and telecom environments. Engineers will appreciate its balance of performance, size, and durability in complex multi-resistor networks.
