GS4B029100DDT Description

The GS4B029100DDT from TT Electronics/IRC is a high-precision 7-resistor thin-film network in an 8-pin SOIC gull-wing SMD package. Designed for BUS circuit applications, it offers a 910Ω resistance per element with a tight ±0.5% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). The ceramic case and thin-film technology provide excellent thermal performance and reliability, while the 0.4W total power rating (0.05W per resistor) suits moderate-load applications. Its 100V maximum voltage rating and surface-mount design make it ideal for compact, high-density PCB layouts.
