GS4B025111FFT

GS4B025111FFT Description

The GS4B025111FFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for precision applications, it features a 5.11KΩ resistance per element with a tight ±1% absolute tolerance and ±1% ratio tolerance, ensuring consistent performance in critical circuits. The network employs thin-film technology on a ceramic substrate, delivering excellent stability with a low ±50ppm/°C temperature coefficient. Rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation, it operates reliably across a -55°C to +125°C range, with derated performance up to 125°C. Its 100V maximum voltage rating and surface-mount gull-wing termination make it suitable for compact, high-density PCB designs.
