Abstract

The present invention relates to a circuit protection device and provides a circuit protection device comprising a laminate having a plurality of sheets laminated; a magnetic core provided within the laminate; a coil provided within the laminate and configured to wind vertically and to wrap the magnetic core; a projecting electrode connected to the coil and projected to be exposed to the outside of the laminate; and an external electrode provided on the laminate and connected to the projecting electrode.

Description

technical field [0001] The present invention relates to a circuit protection device, more particularly to a circuit protection device for suppressing noise in an electronic device. Background technique [0002] Recently, various frequency bands have been used in accordance with the versatility of portable electronic devices such as smartphones. That is, different frequency bands are used for wireless LAN, Bluetooth, GPS, etc. in one smartphone. Specifically, electromagnetic interference (EMI) has been strictly controlled so as to avoid influence on communications using GHz frequency bands such as wireless LAN and GPS. In fact, since October 2010, EMI has been controlled up to 6GHz in Europe and Japan, so EMI greater than 1GHz should be limited. Furthermore, since such electronic devices are highly integrated, the density of internal circuits increases within a limited space. Therefore, noise interference between internal circuits basically occurs. [0003] In order to su...
