What is the difference in parasitic capacitance of common mode inductors under different winding methods?

Time：2025-12-30 Views：55次

Share：

Parallel winding: large inter-turn capacitance, with parasitic capacitance reaching tens of pF.

Slot-wound: Reduces inter-turn coupling, and parasitic capacitance can be reduced by 30%-50%.

Multi-layer winding: Interlayer capacitance dominates, with parasitic capacitance being 2-3 times higher than that of single-layer.
