GQ8A021001JFT Description

The GQ8A021001JFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low thermal drift. This 8-resistor isolated network features a 1K Ohm resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (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 compact, high-density PCB designs. The gull-wing SMD termination ensures secure surface mounting, while the 100V maximum voltage rating enhances durability in demanding circuits.

GQ8A021001JFT Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Ceramic Case Style: Provides superior thermal stability and mechanical robustness compared to plastic alternatives.
• Thin-Film Technology: Delivers low noise, high accuracy, and excellent long-term stability.
• Compact QSOP Package (4.9mm x 6.02mm x 1.47mm): Ideal for space-constrained applications.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• High Power Density: 0.75W total rating in a miniature footprint, outperforming similar networks with lower power handling.
