GS4A034301FFT

GS4A034301FFT Description

The GS4A034301FFT from TT Electronics/IRC is a high-precision 4-resistor network designed for demanding isolation and signal conditioning applications. Housed in an 8-pin narrow SOIC ceramic package, it features isolated thin-film resistors with a 4.3KΩ resistance value and a tight ±1% absolute tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in harsh environments. Its ±25ppm/°C temperature coefficient minimizes drift, while the 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for precision analog circuits. The gull-wing termination and surface-mount design facilitate automated assembly.
