Inductive SMT Components in Comparison – the Wire Makes the Difference

Different construction in apparently similar inductive SMT components lead to different performance results. This application note concisely shows the differences between three different inductive SMT components – the ceramic inductor (air coil), the SMT ferrite and the wire-wound ferrite inductor. Electrical parameters are compared and their differences explained. Not always induced parasitic parameters are a nuisance. The application note illustrates how the components can be used to the best performance and how these parasitic parameters can be utilized advantageously in circuit design.
