Learn more about the magnetic toroidal coil inductor winding copper wire method

1. Single-layer winding as much as possible: When space allows, try to use a larger core, which will make the coil a single layer and effectively reduce the inter-turn capacitance.
2、Input and output away from each other: No matter what form of inductor is made, the input and output of the coil should be away from each other, otherwise the capacitance between input and output will short out the whole inductor.
3、Multi-layer winding method: When the coil has more turns and must be wound in multiple layers, it should be wound in one direction, overlapping while winding, not winding back after one layer.
4、Segmental winding: The coil is wound in segments on a core, so that the capacitance of each segment is smaller, and the total parasitic capacitance is a series connection of the parasitic capacitance on two segments, and the total capacity is smaller than the parasitic capacity of each segment.
5、Multiple inductors in series: A large inductor can be decomposed into a larger inductor and several smaller inductors with different inductance, and connecting these inductors in series can make the bandwidth of the inductor expand.
