GS8A011581CAT Description

The GS8A011581CAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 16-pin narrow SOIC package, this device features 8 isolated thin-film resistors, each with a resistance value of 1.58KΩ and an absolute tolerance of ±0.25%. The network operates over a wide temperature range of 70°C to 125°C with a derated power rating, ensuring reliability in thermally challenging environments. Its ±100ppm/°C temperature coefficient and 0.1W (1/10) power rating per resistor make it suitable for precision circuits requiring stable performance. The SOIC-C series construction offers robust ceramic case durability, while the gull-wing termination facilitates easy surface mounting.
