GS4A0376R8GDT Description

The GS4A0376R8GDT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding circuit isolation applications. Built with ceramic substrate and thin-film technology, it delivers a stable 76.8Ω resistance per element with a tight ±2% absolute tolerance and ±0.5% ratio tolerance, ensuring exceptional matching accuracy. The device operates over a wide temperature range (-70°C to +125°C) with a low ±25ppm/°C temperature coefficient, making it ideal for environments requiring thermal stability. Its 100V maximum voltage rating and 0.1W power dissipation per resistor (0.4W total) suit precision analog and digital circuits. The gull-wing termination and surface-mount design (4.9mm x 5.99mm footprint) facilitate automated assembly.
