GS4A0373R2FT Description

The GS4A0373R2FT from TT Electronics/IRC is a high-precision 4-resistor network designed for isolation applications (ISOL) in demanding electronic circuits. Housed in an 8-pin narrow SOIC (SOIC-C Series) ceramic package, it features 73.2Ω thin-film resistors with a tight ±1% tolerance and an ultra-stable ±25ppm/°C temperature coefficient. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and digital systems. The gull-wing termination and 1.27mm terminal pitch ensure compatibility with standard SMT assembly processes.
