GS4B031821FFT

GS4B031821FFT Description

The GS4B031821FFT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable resistance values and tight tolerances. Built with thin-film technology on a ceramic substrate, it offers excellent thermal stability with a ±25ppm/°C temperature coefficient and a 1% absolute tolerance. The network features a 1.82KΩ resistance per element, rated for 0.05W (1/20W) per resistor and 0.4W total power dissipation. Its SOIC-C series construction ensures reliability in harsh environments, with an operating temperature range of 70°C to 125°C and a 100V maximum voltage rating. The gull-wing termination and surface-mount design facilitate automated assembly, while the ±0.1mm height/length tolerances ensure consistent PCB placement.
