GS4A012201GFT Description

The GS4A012201GFT from TT Electronics/IRC is a high-performance 4-resistor isolated network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film resistance. With a 2.2KΩ resistance per element, it offers a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in differential circuits. The ceramic-based construction enhances thermal stability, supporting operation from 70°C to 125°C with a ±100ppm/°C temperature coefficient. Rated for 100V maximum voltage and 0.1W power per resistor, it suits low-power, high-reliability designs. The gull-wing termination and 1.27mm pitch facilitate easy surface-mount assembly.
