GS7A034990JGT Description

The GS7A034990JGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values across a wide temperature range. This 14-pin narrow SOIC package features 7 isolated thin-film resistors, each with a 499Ω resistance and a ±5% absolute tolerance. The device operates within a temperature range of 70°C to 125°C and offers a low temperature coefficient of ±25ppm/°C, ensuring minimal resistance drift. With a power rating of 0.7W (0.1W per resistor) and a maximum voltage rating of 100V, it is engineered for reliability in demanding environments. The SOIC-C series construction provides robust mechanical stability, while the gull-wing termination facilitates easy surface-mount assembly.
