GQ0A025490DBT Description

The GQ0A025490DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 549 Ω resistance value and an exceptional ±0.5% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a ±50 ppm/°C temperature coefficient and a maximum operating temperature of 125°C. The gull-wing termination ensures reliable surface-mount assembly, while the 0.1W power rating per resistor (1W total) and 100V maximum voltage rating make it suitable for precision analog and digital circuits.

GQ0A025490DBT Features

• High Precision: ±0.5% tolerance and ±50 ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case provides excellent thermal and mechanical stability.
• Isolated Resistors: 10 independent resistors (549 Ω each) with 100V isolation, ideal for signal conditioning.
• Surface-Mount Design: Gull-wing terminals and 0.64mm pitch enable compact PCB layouts.
