GQ0A027872DBT Description

The GQ0A027872DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 78.7KΩ resistance value and a tight 0.5% tolerance, ensuring exceptional accuracy. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C and a ±50ppm/°C temperature coefficient. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 0.1W power rating per resistor (1W total) and 100V maximum voltage rating make it suitable for high-reliability circuits.

GQ0A027872DBT Features

• Precision Performance: 0.5% tolerance and ±50ppm/°C TCR ensure stable operation across a 70 to 125°C derated power range.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength, ideal for harsh environments.
• Compact & Efficient: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances enable high-density layouts.
• Isolated Design: 10 resistors with independent isolation (ISOL) reduce crosstalk in sensitive analog/digital systems.
• Surface-Mount Ready: Gull-wing leads with 0.64mm pitch simplify automated assembly processes.
