GS4A034122JFT Description

The GS4A034122JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values across varying temperatures. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a 41.2KΩ resistance and a ±5% absolute tolerance, ensuring consistent performance in demanding environments. With a ±25ppm/°C temperature coefficient, this network offers excellent thermal stability, making it suitable for circuits where minimal drift is critical. The SOIC-C series construction provides robust mechanical durability, while the gull-wing termination ensures reliable surface-mount compatibility. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it operates within a 70°C to 125°C derated power range, with a 125°C maximum operating temperature.
