GQ8A021272JFT Description

The GQ8A021272JFT 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 12.7KΩ resistance per element with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range of 70°C to 125°C. Housed in a 16-pin QSOP ceramic package, it offers a 0.75W (3/4W) total power rating and 0.1W per resistor, making it suitable for compact, high-density PCB designs. The gull-wing termination and surface-mount (SMD) configuration facilitate easy assembly, while its 100V maximum voltage rating enhances durability in demanding circuits.

GQ8A021272JFT Features

• Isolated Circuit Design (ISOL): Each resistor operates independently, reducing crosstalk in multi-channel systems.
• Ceramic Case & Thin Film Technology: Delivers superior thermal stability and low noise compared to thick-film alternatives.
• Precision Tolerance & TCR: ±5% resistance tolerance and ±50ppm/°C ensure consistent performance under thermal stress.
• Compact QSOP Package: Measures 4.9mm (L) × 6.02mm (D) × 1.47mm (H) with tight tolerances (±0.1mm height/length), ideal for space-constrained applications.
• High Power Handling: 0.75W total dissipation (0.1W per resistor) supports robust operation in power-sensitive designs.
