GS4B0254R9FT

GS4B0254R9FT Description

The GS4B0254R9FT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package, designed for space-constrained surface-mount applications. Featuring a 54.9Ω resistance per element with a tight ±1% tolerance, this ceramic-based thin-film network ensures stable performance across a wide temperature range (70°C to 125°C). Its ±50ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for demanding environments. The 0.05W (1/20W) power rating per resistor and 0.4W total power dissipation balance compactness with reliability.
