Coil component

A coil component, comprising:

• a coil portion having a core disposed through a central portion thereof;
• a body encapsulating the coil portion and the core;
• a first external electrode and a second external electrode disposed to be spaced apart from each other on a surface of the body and connected respectively to a first end and a second end of the coil portion;
• a third external electrode disposed on the body to be spaced apart from the first and second external electrodes;
• and
• a noise removal portion having opposing ends connected to the third external electrode such that the noise removal portion and a portion of the third external electrode together form at least one loop surrounding the coil pattern without surrounding the core,
• wherein the noise removal portion is insulated from the coil portion and the core.
