GQ8A021821FAT Description

The GQ8A021821FAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 8-resistor array features a 1.82KΩ resistance value per resistor with a tight 1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic QSOP package, it offers excellent thermal stability and durability. The 16-pin gull-wing SMD termination facilitates reliable surface-mount assembly, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for moderate power applications.

GQ8A021821FAT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±50ppm/°C) for stable operation.
• Robust Ceramic Package: Enhances thermal performance and mechanical strength in harsh environments.
• Compact QSOP-16 Form Factor: Space-saving 4.9mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances.
• Isolated Resistor Design (ISOL): Each resistor operates independently, ideal for multi-channel circuits.
• High Voltage Rating (100V): Supports applications requiring elevated voltage handling.
