GQ8A037500FFT

GQ8A037500FFT Description

The GQ8A037500FFT 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 750Ω resistance per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide -70°C to +125°C operating range. Rated for 0.1W (1/10W) per resistor and 0.75W (3/4W) total power dissipation, it supports 100V maximum voltage and features gull-wing terminations for reliable surface-mount (SMD) assembly. Its 16-pin configuration and isolated (ISOL) circuit design make it ideal for space-constrained PCBs requiring signal isolation or impedance matching.

GQ8A037500FFT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy (±25ppm/°C) for sensitive analog/digital circuits.
• Robust Ceramic QSOP Package: Enhances thermal performance and mechanical durability in harsh environments.
• High Power Density: 0.75W total rating (0.1W per resistor) in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• Isolated Resistor Network: Independent resistors (ISOL design) prevent crosstalk, ideal for multi-channel systems.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, suitable for industrial and automotive-grade prototypes (though not PPAP/automotive-certified).
