GS4B034020DBT Description

The GS4B034020DBT 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 402Ω resistance per element with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide operating range of -70°C to +125°C. The ceramic case and thin-film technology provide excellent thermal stability and reliability, while the 0.4W total power rating (0.05W per resistor) suits moderate power dissipation needs. Its 100V maximum voltage rating and surface-mount design make it ideal for compact, high-density PCB layouts.
