GS4B034120CT Description

The GS4B034120CT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package. Designed for surface-mount applications, it features a 412Ω resistance per element with an ultra-tight ±0.25% absolute tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The thin-film technology delivers superior accuracy and reliability, while the gull-wing termination facilitates robust PCB mounting. With a 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network is engineered for demanding circuits requiring minimal drift and high consistency.
