1. Good high-frequency performance
Air core inductors have no iron core, so there is no hysteresis, eddy current loss and magnetic saturation problems of the iron core at high frequencies. They can maintain good performance in high-frequency circuits, with low signal distortion, and are suitable for processing high-frequency alternating currents. For example, in radio frequency communication circuits, they can achieve accurate processing and transmission of high-frequency signals.
2. High linearity
The inductance value is basically independent of the current passing through it. Under different current conditions, the inductance value is relatively stable and has good linear characteristics. This enables Air core inductors to work accurately in some circuits with high linearity requirements, such as precision measurement circuits and audio amplifier circuits, and will not cause large fluctuations in inductance value due to current changes, thereby ensuring the stability and accuracy of circuit performance.
3. Low electromagnetic interference
Since there is no iron core to gather and enhance the magnetic field, the magnetic field radiated outward by the Air core inductor is relatively weak, and the electromagnetic interference generated by itself is small, and it is also not easily disturbed by external magnetic fields. In some electronic devices with high requirements for electromagnetic compatibility, such as aerospace electronic equipment, medical electronic equipment, etc., this feature of Air core inductor enables it to better meet the electromagnetic compatibility design requirements of the equipment, ensure the normal operation of the equipment, and reduce interference with other electronic components and equipment.
4. Simple structure
Air core inductor is usually made by directly winding the coil, without complex structures such as iron core, and the manufacturing process is relatively simple and the cost is low. Moreover, its structure is simple, small in size, light in weight, easy to install and integrate in various electronic devices, which can effectively save circuit board space and improve the compactness and portability of the equipment.
5. Good temperature stability
The inductance value of the Air core inductor changes little under different temperature environments. Because there is no iron core material, the magnetism of the iron core will not change due to temperature changes, thereby affecting the inductance value. This feature enables it to maintain stable performance in various harsh temperature environments, such as high temperature industrial environments, low temperature outdoor environments, etc., to ensure the normal operation of the circuit.
