GQ8A021071DBT Description

The GQ8A021071DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor network features a 1.07KΩ resistance value with an ultra-tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers 0.75W (3/4W) total power dissipation and 0.1W per resistor, making it suitable for high-density PCB designs. The gull-wing termination and surface-mount (SMD) compatibility facilitate automated assembly, while its 100V maximum voltage rating enhances reliability in industrial and telecom environments.

GQ8A021071DBT Features

• Precision Thin Film Technology: Delivers superior accuracy (±0.5%) and low TCR (±50ppm/°C) for stable operation.
• Robust Ceramic QSOP Package: Ensures thermal stability and mechanical durability in harsh conditions.
• High Power Handling: 0.75W total power rating (0.1W per resistor) for energy-efficient designs.
