This close contact makes heat unable to effectively spread, easily leading to the temperature of the inductance structure being too high during operation, thereby affecting its performance and service life. Poor heat dissipation can also cause the inductance structure to be saturated, reducing its inductance value, and even damaging the inductance structure. At the same time, when the distance between multiple turns of coils is too close, parasitic capacitance is generated, which can significantly affect the performance of the inductance structure.
