PQ32 DIP Power Inductors Manufacture Customized DW6465A
The inductor have three important parameters:
(I) Inductance
The inductance is decide of the turn, the material of the magnetic
core, etc. Usually, the turn is more,the inductance is bigger. The
larger the magnetic permeability of the core, the inductance is
bigger.
(II) Allowable Tolerance
It refers to the allowable error value between the nominal
inductance on the spec with the actual inductance.The allowable
tolerance is ± 10% ~ 15%.
(III) Rated current
It refers to the maximum current value that the inductor is allowed
to pass during normal operation. If the working current exceeds the
rated current, the inductor will change performance parameters due
to heat generation, and even burn out due to over current.
