GQ8A011272FAT

GQ8A011272FAT Description

The GQ8A011272FAT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a ceramic QSOP package, this 16-pin SMD component offers 12.7KΩ resistance per resistor with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in demanding circuits. The isolated (ISOL) circuit design allows independent resistor operation, while the gull-wing termination ensures secure surface mounting.

GQ8A011272FAT Features

• Precision Thin-Film Technology: Delivers low noise and high accuracy (±1%) for sensitive analog/digital systems.
• Robust Ceramic QSOP Package: Enhances thermal performance and durability in harsh environments.
• Wide Temperature Range: Stable operation from 70°C to 125°C with derated power handling.
• High Power Density: 0.75W total dissipation (0.1W per resistor) in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• Isolated Resistor Network: Independent resistors (ISOL) enable flexible circuit design without crosstalk.
• Surface-Mount Gull Wing Terminals: Facilitates automated PCB assembly with a 0.64mm pitch.

GQ8A011272FAT Applications

Ideal for precision instrumentation, medical devices, and industrial control systems where stability and space efficiency are critical. Key use cases include:

• Voltage dividers and signal conditioning in data acquisition systems.
• Feedback networks for op-amps and ADCs/DACs.
• Impedance matching in high-frequency communication equipment.
• Automotive and aerospace subsystems (non-automotive grade, but suitable for benign environments).

Conclusion of GQ8A011272FAT

The GQ8A011272FAT excels in high-density, precision circuits requiring low TCR, tight tolerance, and isolation. Its ceramic construction, thin-film technology, and gull-wing SMD design make it a superior choice over bulkier or less stable alternatives (e.g., thick-film networks). While not RoHS-compliant or PPAP-certified, it remains a cost-effective solution for industrial, telecom, and test/measurement applications demanding long-term reliability.
