A air core inductor is an inductor component without a magnetic iron core inside. Its magnetic path is mainly composed of air. Therefore, theair core inductor avoids hysteresis loss and eddy current loss, and its operating frequency can be very high. Since the magnetic permeability comes from air, the inductance value (L) does not change with the current, there is no magnetic saturation phenomenon, and it can maintain the inductance value stable even when a large current passes through. Therefore, this air core inductor is highly suitable for use in filtering and power applications involving high currents or significant current fluctuations.

Other types besides the above listed can be produced according to customer’s needs.
1. When using it, it should be noted that its radiation magnetic field may cause interference to nearby sensitive circuits. In such cases, it is necessary to maintain a distance or add shielding.
2. Avoid external impacts or compressions on the coil to prevent any changes in its geometric shape, which could lead to variations in the inductance value.
