GS4A024022FT Description

The GS4A024022FT from TT Electronics/IRC is a high-performance 4-resistor isolated network designed for precision applications. Housed in an 8-pin narrow SOIC ceramic package, it features 40.2KΩ thin-film resistors with a tight ±1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The SOIC-C series construction provides excellent thermal and mechanical reliability, with a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating. Its gull-wing termination and surface-mount design facilitate automated assembly, while the isolated circuit design (designated "ISOL") eliminates crosstalk between resistors.
