GQ8A025490FAT

GQ8A025490FAT Description

The GQ8A025490FAT from TT Electronics/IRC is a high-performance 8-resistor thin film network designed for precision applications. Encased in a ceramic QSOP package, it offers a 549Ω resistance per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. The 16-pin gull-wing SMD configuration and 0.64mm terminal pitch facilitate compact PCB layouts, while its 0.75W total power rating (0.1W per resistor) balances efficiency and thermal management. The isolated (ISOL) circuit design minimizes crosstalk, making it ideal for signal integrity-critical systems.

GQ8A025490FAT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±50ppm/°C) for sensitive analog/digital circuits.
• Robust Ceramic Package: Enhances thermal performance and durability in harsh environments.
• High Voltage Tolerance: Supports up to 100V, suitable for industrial and automotive-grade designs (though not PPAP/Automotive certified).
• Compact QSOP-16 Form Factor: 4.9mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances enable high-density mounting.
• Gull Wing Termination: Ensures reliable solder joints for surface-mount assembly.
• Non-RoHS Compliance: Preferred for legacy or specialized applications requiring traditional materials.
