GS8A014991DBT Description

The GS8A014991DBT from TT Electronics/IRC is a high-precision 8-resistor network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin narrow SOIC ceramic package, it features isolated thin-film resistors with a 4.99KΩ resistance value and an absolute tolerance of ±0.5%, ensuring exceptional accuracy. The device operates over a wide temperature range of 70°C to 125°C (derated) with a maximum operating temperature of 125°C, making it suitable for harsh environments. Its ±100ppm/°C temperature coefficient and 0.1W (1/10) power rating per resistor contribute to stable performance under varying thermal conditions. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating ensures reliability in high-voltage circuits.
