GS4A021271GAT Description

The GS4A021271GAT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 1.27KΩ and a tight ±2% absolute tolerance. The network operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±50ppm/°C, ensuring stable performance under thermal stress. Encased in a rectangular ceramic SOIC package, it offers excellent durability and thermal conductivity. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, this component is ideal for demanding circuit designs requiring isolation and precision.

GS4A021271GAT Features
