GS4A021740DDT Description

The GS4A021740DDT by TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for demanding surface-mount applications. It features 174Ω resistance per element with an absolute tolerance of ±0.5% and a ratio tolerance of ±0.5%, ensuring exceptional accuracy. The thin-film technology delivers a low temperature coefficient of ±50ppm/°C, stable across a wide operating range of -70°C to +125°C. With a 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating, this network is engineered for reliability in precision circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate easy PCB integration.
