GS4A0273R2JFT Description

The GS4A0273R2JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features a 73.2Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±1%, ensuring consistent performance in matched circuits. Its thin-film technology and ±50ppm/°C temperature coefficient provide excellent stability across a wide operating range of -55°C to +125°C, derated up to 70°C to 125°C. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, it is suited for demanding environments. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case ensures durability and thermal resistance.
