The insulation performance of Nanocrystalline Common Mode Inductor will change significantly under different humidity environments.
When in an environment with high humidity, the water vapor content in the air increases. First, the water vapor may be adsorbed on the surface of the Nanocrystalline Common Mode Inductor. If the moisture resistance of its outer insulating material is not good, the water vapor may gradually penetrate into the inner part of the insulating layer. This will cause the insulation resistance to decrease, because water has a certain conductivity, and even a trace amount of water entering the insulating layer may form a conductive path, thereby reducing the insulation performance of the inductor. For example, an inductor that can withstand higher voltages without leakage may leak at lower voltages after the humidity increases, affecting the normal operation and safety of the circuit.
On the other hand, changes in humidity may cause changes in the physical properties of the insulating material. In a high humidity environment, some insulating materials may absorb water and expand. For Nanocrystalline Common Mode Inductor, this expansion may cause tiny cracks or delamination in the insulating layer. Once these defects appear in the insulating layer, it is easier for water vapor to penetrate further into the interior, further deteriorating the insulation performance. Moreover, as time goes by, under the combined effects of humidity and electric field, aging and degradation of the insulating material may occur, causing the insulation performance to continue to decline.
However, in a dry environment with low relative humidity, the insulation performance of Nanocrystalline Common Mode Inductor is relatively good. But if the environment is too dry, there may be some problems. For example, dry air may cause the accumulation of static electricity, and when the static electricity is released, it may cause a momentary high voltage shock to the insulation layer of the inductor. Although this situation is relatively rare, it may also have a certain impact on the insulation performance. In short, in order to ensure that Nanocrystalline Common Mode Inductor can maintain good insulation performance under different humidity environments, it is necessary to select suitable insulating materials during the design and manufacturing process, and take effective moisture and humidity prevention measures. At the same time, various problems that may arise under different humidity conditions must also be considered to ensure the reliability of the inductor and the normal operation of the circuit.
