I do not know so much about the two kind of components in the following passage .So I can only do some introduction.The SMD power inductor is really a useful thing which adopt the design structure of open magnetic circuit.Established in 2005,we specialize in SMD power indunctor,Choke Coil Suppliers & manufacturers,coil,and voltage transformer. And choke coil is the component of the similar function.In my opinion, the two things are very useful for some electrical industries.Someone who need these may see this ad and want to have a deal with the company.If you have some interest in any of two conponents, please clike the linkage.
