GQ8B014991JDT Description

The GQ8B014991JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 16-pin QSOP (Quarter-Small Outline Package) device integrates 15 resistors, each with a 4.99KΩ resistance and a 5% tolerance, making it ideal for bus termination, voltage division, and signal conditioning in compact PCB designs. The ceramic case ensures excellent thermal stability, while the gull-wing termination facilitates reliable surface-mount assembly. With a power rating of 0.75W (3/4W) total (0.05W per resistor) and a ±100ppm/°C temperature coefficient, this network delivers consistent performance across a wide temperature range (70°C to 125°C).

GQ8B014991JDT Features

• High-Density Integration: 15 resistors in a 4.9mm × 6.02mm × 1.47mm QSOP package, saving board space.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical durability.
• Precision Performance: ±5% tolerance and ±100ppm/°C TCR ensure stability in varying environments.
• Wide Voltage Range: Supports up to 100V maximum voltage, suitable for industrial applications.
• Surface-Mount Ready: Gull-wing leads with 0.64mm pitch for automated assembly compatibility.
• Non-Automotive Grade: Optimized for general-purpose electronics, though not PPAP-certified.

GQ8B014991JDT Applications

This resistor network excels in:

• Bus Termination: Ensures signal integrity in high-speed digital circuits (e.g., memory modules, FPGAs).
• Analog Signal Processing: Used in DAC/ADC reference networks and sensor interfaces.
• Power Distribution: Divides voltage rails in low-power embedded systems.
• Industrial Controls: Reliable operation in test equipment, instrumentation, and communication devices.

Conclusion of GQ8B014991JDT

The GQ8B014991JDT combines compact design, precision resistance, and thermal resilience, making it a versatile choice for space-constrained, high-reliability applications. While not RoHS-compliant, its ceramic construction and thin-film technology offer superior performance over standard thick-film networks. Engineers will appreciate its balance of power handling, tolerance, and integration density, particularly in digital and mixed-signal systems requiring stable resistive loads.
