GQ8A0147R5FCT Description

The GQ8A0147R5FCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor isolated network features a 47.5Ω resistance per element with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 16-pin QSOP ceramic package, it offers excellent thermal stability and durability, making it ideal for demanding environments. The 0.75W (3/4W) total power rating and 0.1W per resistor provide robust power handling, while the 100V maximum voltage rating ensures reliability in high-voltage circuits.

GQ8A0147R5FCT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±100ppm/°C) for stable performance.
• Ceramic QSOP Package: Enhances thermal management and mechanical strength, suitable for harsh conditions.
• Isolated Circuit Design (ISOL): Each resistor is electrically isolated, enabling flexible circuit configurations.
• Gull Wing Termination: Facilitates reliable surface-mount (SMD) assembly with a 0.64mm pitch for high-density PCB layouts.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Compact Dimensions: 4.9mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D) for space-constrained designs.

GQ8A0147R5FCT Applications

This resistor network excels in precision analog and digital circuits, including:

• Signal Conditioning: Ideal for op-amp feedback networks and voltage dividers in instrumentation.
