GS4A034871JFT Description

The GS4A034871JFT from TT Electronics/IRC is a high-performance 4-resistor isolated network designed for precision applications in demanding environments. Housed in an 8-pin narrow SOIC ceramic package, it features 4.87KΩ thin-film resistors with an absolute tolerance of ±5% and a ratio tolerance of ±1%. The device operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±25ppm/°C, ensuring stable performance under thermal stress. Its 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for high-reliability circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and thermal dissipation.
