GQ0A024990CBT Description

The GQ0A024990CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 499 Ω resistance value and an ultra-tight ±0.25% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±50 ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount (SMD) assembly, while the 0.64 mm terminal pitch facilitates high-density PCB layouts. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision signal conditioning, isolation, and voltage division in critical circuits.

GQ0A024990CBT Features

• High Precision: ±0.25% tolerance and ±50 ppm/°C TCR ensure minimal drift in sensitive applications.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal and long-term stability.
• Isolated Design: 10 independent resistors (ISOL circuit designator) for flexible circuit integration.
• Space-Efficient: Compact QSOP package (8.66 x 6.02 x 1.47 mm) with gull-wing leads for SMD compatibility.
• Wide Operating Range: Derated power up to 125°C, suitable for industrial and automotive-adjacent environments (though not PPAP/AEC-Q200 certified).
• High Voltage Handling: 100V rating per resistor, ideal for analog and mixed-signal systems.

GQ0A024990CBT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and gain setting in op-amp designs.
• Signal Isolation: Buffering and impedance matching in communication interfaces (e.g., RS-485, CAN).
• Test & Measurement Equipment: Calibration references and sensor signal conditioning.
• Industrial Controls: PLCs, motor drives, and power supply feedback loops requiring stable resistance under thermal stress.
• Medical Electronics: Isolated signal paths in diagnostic devices where accuracy is critical.

Conclusion of GQ0A024990CBT
