The number of coil turns can be significantly reduced by using a magnetic core.
Under the condition of satisfying the requirements of volume and so on, the coil diameter is appropriately selected to be larger, which is beneficial to reduce the loss. The coil diameter is selected to be larger, and the volume is increased to reduce the coil loss.
Generally used in the receiver coil, single layer coil diameter of 12mm-30mm; The multi-layer coil shall be 6mm-13mm, but it shall not exceed the range of 20mm-25mm in terms of volume.
We are the professional manufacture of Common Mode Choke Core manufacturer, please see the Toroidal Ferrite Core Inductor design.
