GS4B021432FFT

GS4B021432FFT Description

The GS4B021432FFT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC package. Designed for surface-mount applications, it features a 14.3KΩ resistance per element with an absolute tolerance of ±1% and a ratio tolerance of ±1%. The network employs thin-film technology on a ceramic substrate, ensuring low temperature coefficient (±50ppm/°C) and stable performance across a wide temperature range (70°C to 125°C). With a power rating of 0.4W (0.05W per resistor) and 100V maximum voltage rating, it is ideal for precision analog and digital circuits. The gull-wing termination and SOIC package facilitate easy PCB integration, while the non-automotive, non-PPAP compliance suits industrial and commercial applications.
