GS4A025490GFT Description

The GS4A025490GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 549Ω resistance and a tight ±2% absolute tolerance (with ±1% ratio tolerance). Built with ceramic substrate technology, it offers excellent thermal stability with a ±50ppm/°C temperature coefficient, ensuring reliable performance across a wide temperature range (70°C to 125°C). The SOIC package (4.9mm × 5.99mm × 1.45mm) provides compact, surface-mount compatibility, while the gull-wing termination ensures secure PCB attachment. Rated for 0.1W per resistor (0.4W total) and 100V maximum voltage, it is ideal for high-density circuits requiring precision and durability.
