GS4A034302FBT Description

The GS4A034302FBT from TT Electronics/IRC is a high-precision 4-resistor network in an 8-pin narrow SOIC package, designed for isolated circuit applications. Built with ceramic substrate and thin-film technology, it delivers exceptional stability with a ±25ppm/°C temperature coefficient and ±1% absolute tolerance. The network features 43kΩ resistance per element, rated for 0.1W (1/10W) per resistor (0.4W total), and operates across a wide temperature range of -70°C to +125°C. Its 100V maximum voltage rating and 1.27mm terminal pitch make it suitable for dense PCB layouts. The gull-wing termination ensures reliable surface-mount assembly, while the rectangular ceramic case enhances thermal performance.
