The difference of I- type inductor and SMD winding inductor

The difference between I- type inductor and SMD winding inductor the most basic difference is that the patch winding inductor is patch type without pin, I-word inductor is plug-in type with pin, wave type will also have a difference.
The I-type  inductor is an electromagnetic induction component composed of a hard-shaped magnetic core skeleton and an enameled copper wire. It is a component that can convert the electrical signal into a magnetic signal. The I-type inductance itself is an inductor. The skeleton of the I-word inductor is supported by the winding of the copper core coil. I-word inductor is one of the properties of the electronic circuit or device, refers to: when the current changes, due to electromagnetic induction and resistance to current change of electric dynamic potential some larger volume of fixed inductor or adjustable inductor (such as oscillation coil, flow circle, etc.) the characteristics of I-Shape  inductor: with high power and high magnetic saturation, low impedance, small size.

I-type inductor and patch winding inductor, patch inductor, also known as power inductor, large current inductance. It has the characteristics of miniaturization, high quality, high energy storage and low resistance. Patch inductance is divided into again: winding type, laminated type, woven type. Power patch inductance is divided with magnetic cover and no magnetic cover, mainly composed of magnetic core and copper wire. In the circuit mainly play a filtering and oscillating role
