GS7B026490GT

GS7B026490GT Description

The GS7B026490GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 14-pin narrow SOIC device features 13 bussed resistors with a 649Ω resistance value and a tight ±2% tolerance, ensuring reliable signal integrity in demanding circuits. Built with thin-film technology, it offers a low ±50ppm/°C temperature coefficient, making it stable across a wide operating temperature range of -70°C to +125°C. The SOIC package (8.66mm x 5.99mm x 1.45mm) with gull-wing termination ensures compatibility with automated surface-mount assembly processes. Rated for 100V maximum voltage and 0.7W total power dissipation, it is ideal for high-density PCB designs requiring consistent performance under thermal stress.
