GS4B023922FDT Description

The GS4B023922FDT 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 39.2KΩ resistance per element with a tight ±1% absolute tolerance and ±0.5% ratio tolerance, ensuring consistent performance in critical circuits. The thin-film technology and ceramic case provide excellent stability, with a low ±50ppm/°C temperature coefficient, making it ideal for environments with fluctuating temperatures. Rated for 0.05W (1/20W) per resistor and 0.4W total power, it operates reliably up to 125°C, with derating applied from 70°C to 125°C. The 100V maximum voltage rating and gull-wing termination suit high-density surface-mount (SMD) designs.
