how i can connect an inductor which has 4 terminals???
and what is the the difference between it and two terminal inductor??

 

It may be a transformer.

Hello,

It could be a Current-Compensated Ring Core Double Choke.
These are used at the input of a smps for line filtering.

Attached is a datasheet from epcos with closed housings, bit the inner is the same.

What are you attempting to use it for? Are there any markings on yours that would indicate value?

More than two leads usually indicates a transformer or a multi-tap inductor for either different values or use as an autotransformer.

Perhaps what you have is a common-mode filter.
