GQ0A025490FT Description

The GQ0A025490FT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 549 Ω resistance value and a tight 1% tolerance. The device operates within a wide temperature range of 70°C to 125°C, delivering a power rating of 0.1W per resistor (1W total). Its ceramic case ensures durability, while the gull-wing termination facilitates reliable surface-mount (SMD) assembly. With a ±50ppm/°C temperature coefficient and a maximum voltage rating of 100V, this network is engineered for stability and precision in demanding environments.

GQ0A025490FT Features

• High Precision: Thin-film technology ensures low TCR (±50ppm/°C) and 1% tolerance for consistent performance.
• Robust Construction: Ceramic case and QSOP package provide mechanical strength and thermal stability.
• Isolated Resistors: 10 independent resistors (549 Ω each) enable flexible circuit design, ideal for isolation applications.
• Surface-Mount Ready: Gull-wing terminals and 0.64mm pitch simplify PCB assembly.
• Wide Operating Range: Rated for -55°C to +125°C, suitable for industrial and automotive (non-PPAP) use.
