GS8A025490CT Description

The GS8A025490CT from TT Electronics/IRC is a high-precision, surface-mount resistor network designed for isolation (ISOL) applications. This 8-resistor network features a 549Ω resistance value with an ultra-tight 0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Encased in a ceramic SOIC-16 package with gull-wing leads, it offers 0.1W (1/10W) power dissipation per resistor (0.8W total) and a 100V maximum voltage rating. Its thin-film technology provides superior accuracy and reliability, making it ideal for precision analog and digital circuits.
