GS4A031691GAT Description

The GS4A031691GAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring stable performance across a wide temperature range. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 1.69 kΩ and a tight ±2% absolute tolerance. The device operates within a temperature range of 70°C to 125°C with a low temperature coefficient of ±25 ppm/°C, ensuring minimal resistance drift. Its SOIC-C series construction offers excellent thermal and mechanical stability, making it suitable for precision analog and digital circuits. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this network is ideal for space-constrained, high-reliability designs.
