GS4B022210FT Description

The GS4B022210FT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding electronic circuits. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, this thin-film resistor network offers a 221Ω resistance per element with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient. Rated for 0.05W (1/20W) power dissipation per resistor and 0.4W total power, it operates reliably across a wide temperature range of -70°C to +125°C, making it suitable for industrial and automotive-adjacent environments. The 100V maximum voltage rating and gull-wing termination ensure robust performance in surface-mount applications.
