GQ0A0254R9FT Description

The GQ0A0254R9FT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 54.9Ω resistance, 1% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic substrate, it offers excellent thermal stability and durability. With a 1W total power rating (0.1W per resistor) and a maximum operating temperature of 125°C, this component is engineered for reliability in demanding environments. Its gull-wing termination and 0.64mm terminal pitch ensure compatibility with surface-mount (SMD) assembly processes.

GQ0A0254R9FT Features

• Precision Thin Film Technology: Delivers stable resistance values with low noise and high accuracy.
• Isolated Resistor Design (ISOL): Each of the 10 resistors operates independently, reducing crosstalk in sensitive circuits.
• High Power Handling: 1W total dissipation (0.1W per resistor) with derating up to 125°C.
• Compact & Robust: Ceramic QSOP package (8.66mm x 6.02mm x 1.47mm) ensures mechanical strength and thermal performance.
• Wide Voltage Rating: Supports up to 100V, making it suitable for industrial and instrumentation applications.
• Non-Automotive & Non-PPAP: Ideal for commercial and industrial use where PPAP compliance is not required.

GQ0A0254R9FT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces requiring tight tolerance (±1%).
• Signal Conditioning: Isolation and impedance matching in data acquisition systems.
• Medical & Test Equipment: High-reliability applications where thermal stability (±50ppm/°C) is critical.
• Industrial Control Systems: PLCs, motor drives, and power supplies benefiting from its 100V rating and ceramic isolation.

Conclusion of GQ0A0254R9FT
