GS8A016490CAT Description

The GS8A016490CAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 16-pin narrow SOIC package, it features 8 isolated thin-film resistors, each with a resistance value of 649Ω and an absolute tolerance of ±0.25%. The device operates over a wide temperature range of -70°C to +125°C, with a derated power range of 70°C to 125°C, ensuring stability in harsh environments. Its ±100ppm/°C temperature coefficient and 0.1W (1/10) power rating per resistor (0.8W total) make it suitable for precision circuits requiring minimal drift. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and thermal performance.
