GS4A0229R4FT

GS4A0229R4FT Description

The GS4A0229R4FT from TT Electronics/IRC is a high-performance 4-resistor network designed for precision applications requiring stable, isolated thin-film resistors. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, it features 29.4Ω resistance per element with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring reliable performance across a 70°C to 125°C derated power range. With a 100V maximum voltage rating and 0.1W power dissipation per resistor (0.4W total), this network is engineered for surface-mount applications demanding minimal drift and high accuracy. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical stability.
