GS4A011581GBT Description

The GS4A011581GBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 1.58KΩ and a tight ±2% absolute tolerance. The network operates over a wide temperature range of 70°C to 125°C with a derated power rating, ensuring reliability in demanding environments. Its ±100ppm/°C temperature coefficient and ±0.1% ratio tolerance make it ideal for applications requiring stable and accurate resistance matching. The SOIC-C series construction provides excellent thermal and mechanical stability, while the gull-wing termination ensures easy surface-mount assembly.
