GS4A032871FFT

GS4A032871FFT Description

The GS4A032871FFT 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 2.87 kΩ resistance value, ±1% absolute tolerance, and ±1% ratio tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a low temperature coefficient of ±25 ppm/°C, ensuring stability in harsh environments. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal and mechanical reliability.
