GS4B021241GFT Description

The GS4B021241GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features 7 bussed resistors with a 1.24KΩ resistance value and a tight ±2% absolute tolerance, ensuring reliable signal integrity. Built with thin-film technology, it delivers excellent stability with a low ±50ppm/°C temperature coefficient, making it ideal for environments with fluctuating thermal conditions. The SOIC package (4.9mm × 5.99mm × 1.45mm) offers a compact footprint, while the gull-wing termination ensures secure surface-mount assembly. Rated for 100V maximum voltage and 0.4W total power dissipation, it operates reliably across a 70°C to 125°C derated power range, with a 125°C maximum operating temperature.
