GQ8A021472GBT Description

The GQ8A021472GBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 16-pin QSOP (Quarter Small Outline Package) device features 8 isolated resistors, each with a 14.7KΩ resistance, a tight 2% tolerance, and a low ±50ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. The gull-wing termination facilitates easy surface-mount (SMD) assembly, while the 0.64mm terminal pitch ensures compatibility with high-density PCB layouts.

GQ8A021472GBT Features

• High Precision: Thin-film technology delivers low TCR (±50ppm/°C) and 2% tolerance for consistent performance.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• Isolated Design: 8 independent resistors (ISOL circuit designator) prevent crosstalk in sensitive circuits.
• Power Handling: 0.1W per resistor (0.75W total) with a 100V maximum voltage rating.
• Compact & Reliable: QSOP package (4.9mm x 6.02mm x 1.47mm) with ±0.1mm length/height tolerances for precise placement.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, suitable for industrial environments.
