GS4A021913FT Description

The GS4A021913FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 191KΩ and a tight ±1% tolerance. The device operates within a temperature range of 70°C to 125°C, with a ±50ppm/°C temperature coefficient, ensuring minimal drift under varying thermal conditions. Its SOIC-C series construction offers robust ceramic encapsulation, enhancing durability and thermal dissipation. Rated for 100V maximum voltage and 0.1W power per resistor (0.4W total), this network is ideal for high-density PCB designs where space and reliability are critical.
