GS7A0139R0GGT Description

The GS7A0139R0GGT from TT Electronics/IRC is a high-performance 7-resistor isolated network in a 14-pin narrow SOIC package, designed for precision applications requiring stable resistance values under varying conditions. Built with ceramic substrate and thin-film technology, it offers a 39Ω resistance per element with an absolute tolerance of ±2% and a ratio tolerance of ±2%. The device operates across a wide temperature range (-70°C to +125°C) with a low temperature coefficient of ±100ppm/°C, ensuring minimal drift. Its 0.1W power rating per resistor (0.7W total) and 100V maximum voltage rating make it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the compact dimensions (8.66mm x 5.99mm x 1.45mm) save board space.
