GS4A039092FT Description

The GS4A039092FT from TT Electronics/IRC is a high-precision 4-resistor network designed for isolation (ISOL) applications in demanding electronic circuits. Housed in an 8-pin narrow SOIC ceramic package, it features 90.9 kΩ thin-film resistors with a tight ±1% tolerance and a low ±25 ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The device is rated for 0.1W per resistor (0.4W total) and supports 100V maximum voltage, making it suitable for precision analog and digital systems. Its gull-wing termination and surface-mount design facilitate automated assembly, while the isolated element configuration enhances circuit flexibility.
