GS4A022101JFT Description

The GS4A022101JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 2.1kΩ resistance and a ±5% absolute tolerance, ensuring consistent performance in demanding environments. With a ±50ppm/°C temperature coefficient, it delivers excellent thermal stability across an operating range of 70°C to 125°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) offers a compact footprint, making it ideal for space-constrained designs. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, this network is suited for low-power analog and digital circuits.
