What is an inductor ?

2019-07-20

The Inductor


An inductor is just a coil of wire around some kind of core. The core could be just air or it could be a magnet.
When you apply a current through the inductor, a magnetic field is created around it.

By using a magnetic core the magnetic field will be much much much stronger.


class D inductor


How to choice a right inductor ?

A:  Considering the using application ,Isat,Irms ,Rdc,operation temperation ,Frequency etc .


Q:   What’s Rated current?

A:  Rated current is the maximum current that can SAFELY pass through the inductor.


Q:   What’s Saturation Current ?

A:   Saturation is the state reached when an increase in applied external magnetic field H cannot increase the magnetization of the material further, so the total magnetic flux density B more or less levels off. (It continues to increase very slowly due to the vacuum permeability.) Saturation is a characteristic of ferromagnetic and ferrimagnetic materials, such as iron, nickel, cobalt and their alloys.


Q:   During usage , why temperature on the surface of inductor is high but output power with lower efficiency ?

A:   Normally have two reasons :

       a- Rdc is high and coil accrue heat .

       b- Choose an incorrect core material , if high frequency , core lose increase .


Q:   What’s the advantage of high current power inductors ?

A:    High current power inductors has higher current which be more power . Max can be over hundreds amperes .

Q:   Why the molding power chokes no noise in application?

A:   Normally noise comes from the coil shakes. Molding power chokes with high pressure to make powder insert in the coil . A lower possibility accrue noise.

What is the magnetic core ?

A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical.

Common magnetic core material have FERRITE CORES and Alloy core.The ferrite core usually are Mn-Zn ferrite, Ni-zn ferrite, Magnesium zinc ferrite.The Alloy core usually are Iron Powder Core, SENDUST CORES, MPP CORES, Ferro-nickel magnetic powder core, Amorphous nanocrystal
