GS7A023090GGT

GS7A023090GGT Description

The GS7A023090GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in a 14-pin narrow SOIC package, it features 7 isolated thin-film resistors, each with a 309Ω resistance and a tight ±2% absolute tolerance. The device operates within a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliability in demanding environments. Its ±50ppm/°C temperature coefficient minimizes resistance drift, making it suitable for precision analog and digital circuits. The SOIC-C series construction offers robust ceramic substrate insulation, enhancing thermal and electrical stability.
