GS8A015490GFT Description

The GS8A015490GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 8-resistor network features a 549Ω resistance per resistor with a tight 2% tolerance and a ±100ppm/°C temperature coefficient, ensuring reliable performance across a wide operating temperature range of -70°C to +125°C. Housed in a 16-pin SOIC ceramic package, it offers 0.8W total power dissipation (0.1W per resistor) and 100V maximum voltage rating, making it suitable for demanding circuit isolation (ISOL) applications. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal and mechanical stability.
