The present invention belongs to the technical field of electronic transformers, and discloses a micro-electronic transformer with high stability, including a bracket structure, a fixing structure, a guide structure and a moisture absorption structure. In the present invention, through the hygroscopic gel plate of the hygroscopic structure, during the daily use of the electronic device, the moisture absorbed by the hygroscopic gel plate will prevent the micro-electronic transformer from being located in an overly dry environment, thereby preventing the occurrence of electrostatic discharge (ESD) and preventing the insulation layer and semiconductor components of the transformer from being damaged; secondly, when the humidity of the surrounding environment rises, the hygroscopic gel plate continues to absorb moisture and expand, and the expansion of the hygroscopic gel plate will push the thermal conductive slider to move in the direction of the blocking plate, thereby making the blocking plate fit the inner wall of the guide frame. At this time, the bottom of the thermal conductive slider covers the first air inlet, preventing the humid air from flowing in the guide frame and corroding the first airway and the second airway, and preventing the guide frame from breaking after long-term corrosion.
