GS4A015490GFT Description

The GS4A015490GFT 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 device features four isolated thin-film resistors, each with a resistance value of 549Ω and a tight ±2% absolute tolerance (with ±1% ratio tolerance). Its SOIC-C series construction ensures robust performance in demanding environments, with a power rating of 0.1W per resistor (0.4W total) and a maximum operating temperature of 125°C. The ±100ppm/°C temperature coefficient guarantees minimal resistance drift across a 70°C to 125°C derated power range, making it ideal for precision analog and digital circuits.
