GS4B032400FBT Description

The GS4B032400FBT from TT Electronics/IRC is a high-precision 7-resistor thin-film network in an 8-pin SOIC (Ceramic) package, designed for surface-mount applications. It features a 240Ω resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The network is rated for 0.4W total power dissipation (0.05W per resistor) and supports a maximum voltage of 100V. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB mounting, while the ceramic case enhances thermal and mechanical durability.
