GS7B014990DDT Description

The GS7B014990DDT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in a 14-pin narrow SOIC package, this bussed (BUS) configuration integrates 13 thin-film resistors, each with a 499Ω resistance and an absolute tolerance of ±0.5%. The device operates over a wide temperature range of -70°C to +125°C, with a derated power capability up to 125°C, ensuring reliability in harsh environments. Its ±100ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor (0.7W total) make it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances thermal stability and durability.
