GS4B028450FT

GS4B028450FT Description

The GS4B028450FT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for precision applications requiring stable thin-film resistance. With a resistance value of 845Ω (±1% tolerance) and a ±50ppm/°C temperature coefficient, this network ensures reliable performance across a wide temperature range (70°C to 125°C). The 0.05W (1/20W) power rating per resistor and 0.4W total power rating make it suitable for low-power circuits, while its 100V maximum voltage rating enhances versatility. The gull-wing termination and surface-mount design facilitate easy PCB integration.
