GS4A031073FT Description

The GS4A031073FT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Packaged in an 8-pin narrow SOIC (SOIC-C series), it features four isolated thin-film resistors, each with a resistance value of 107KΩ and a tight ±1% tolerance. The device operates over a wide temperature range of -70°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in harsh environments. Its ±25ppm/°C temperature coefficient and 0.1W (1/10W) power rating per resistor (0.4W total) make it suitable for precision circuits. The ceramic case and gull-wing termination provide robust mechanical and thermal performance, while the 100V maximum voltage rating ensures safety in high-voltage applications.
