GQ0A026491JAT Description

The GQ0A026491JAT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package features 10 isolated resistors, each with a 6.49KΩ resistance and a 5% tolerance, ensuring reliable performance in demanding circuits. The ceramic case style and gull-wing termination make it ideal for surface-mount technology (SMT) applications. With a power rating of 1W (0.1W per resistor) and a wide operating temperature range of -70°C to +125°C, this network is engineered for stability under varying thermal conditions. Its ±50ppm/°C temperature coefficient and 100V maximum voltage rating further enhance its suitability for precision analog and digital systems.

GQ0A026491JAT Features

• High-Density Integration: 10 resistors in a compact QSOP package (8.66mm x 6.02mm x 1.47mm) save PCB space.
• Robust Construction: Ceramic substrate ensures durability and excellent thermal dissipation.
• Precision Performance: Thin-film technology provides low noise and high stability (±50ppm/°C).
• Isolated Design: Each resistor is electrically isolated (ISOL circuit designator), reducing crosstalk.
• Wide Operating Range: Functions reliably from -70°C to +125°C, even at derated power.
• Surface-Mount Ready: Gull-wing leads with 0.64mm pitch facilitate automated assembly.
