GS8A026490GT

GS8A026490GT Description

The GS8A026490GT from TT Electronics/IRC is a high-performance 8-resistor thin-film network designed for precision applications. Encased in a 16-pin SOIC ceramic package, it offers 649Ω resistance per resistor with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide temperature range (70°C to 125°C). The isolated (ISOL) circuit design provides independent resistors, eliminating crosstalk in sensitive circuits. With a 0.8W total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount (SMD) device is ideal for compact, high-density PCB designs. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable soldering, while the ceramic case enhances thermal and mechanical durability.
