Abstract: A coil component includes: a body; a coil unit disposed in the body; a support substrate unit in contact with the coil unit to support the coil unit, and including first and second support substrates spaced apart from and oppose each other; and first and second external electrodes disposed on a first surface of the body and spaced apart from each other, and respectively connected to the coil unit.

Abstract: A coil component includes a body including a first surface and a second surface opposing in a first direction, a third surface and a fourth surface disposed between the first surface and the second surface and opposing in the second direction, and a fifth surface and a sixth surface disposed between the first surface and the second surface and opposing in the third direction; a coil disposed in the body and forming a plurality of turns; an insulating wall surrounding a side surface of the coil; an insulating layer covering the coil in the third direction; and an external electrode connected to the coil. A length of the insulating layer in the third direction is a1, a length of an outermost side wall in the first direction, disposed on an outermost side of the insulating wall in the first direction, is b, and 2.11%<a1/b<18.01% is satisfied.

Abstract: A coil component includes a body, a support member, a first coil including a first coil portion disposed on one surface of the support member and having one end and the other end being a first lead-out portion and a first connection portion, respectively, a sub-lead-out portion disposed on the other surface of the support member, and a first via connecting the first lead-out portion and the sub-lead-out portion, a second coil disposed on the other surface of the support member and including a second coil portion having one end and the other end being a second lead-out portion and a second connection portion, respectively, and a second via connecting the first and second connection portions, wherein the first via has a diameter greater than a diameter of the second via.

Abstract: A coil component includes: a body having a first surface and a second surface opposing each other; a support member disposed in the body, and having one surface and the other surface opposing each other; a coil including first and second coil portions disposed on the one surface and the other surface of the support member and having at least one turn, respectively, and a via connecting the first and second coil portions; and first and second external electrodes respectively disposed on the first and second surfaces of the body and connected to the coil, wherein the via includes an upper surface in contact with the first coil portion and a lower surface in contact with the second coil portion, and a ratio VDU/VDL of a diameter VDU of the upper surface to a diameter VDL of the lower surface is 1.06 or more and 1.64 or less.

Abstract: A coil component includes: a body; a coil unit disposed in the body; a support substrate unit in contact with the coil unit to support the coil unit, and including first and second support substrates spaced apart from and oppose each other; and first and second external electrodes disposed on a first surface of the body and spaced apart from each other, and respectively connected to the coil unit.

Abstract: A coil component includes: a body having first and second surfaces facing each other, third and fourth surfaces connecting the first and second surfaces and facing each other, and fifth and sixth surfaces connecting the first to fourth surfaces and facing each other; an insulating substrate disposed inside the body; a coil portion disposed on at least one surface of the insulating substrate, connected to a coil portion and an end portion connected to the coil pattern, and including a lead-out portion where one surface is exposed externally of the body; and first and second external electrodes covering the lead-out portion exposed externally of the body. The first external electrode is disposed on at least a portion of each of the first, third, fifth and sixth surfaces, and the second external electrode is disposed on at least a portion of each of the second, third, fifth, and sixth surfaces.

Abstract: Proposed is a portable laser weapon. The portable laser weapon includes: a laser generation unit generating a high-power laser beam; a wearing unit having the laser generation unit therein and being able to be worn on an individual; a sighting-shooting unit receiving and shooting a laser beam generated from the laser beam generation unit; and a beam transmission cable connecting the laser generation unit and the sighting-shooting unit to each other, thereby transmitting a laser generated from the laser generation unit to the sighting-shooting unit. Accordingly, it is possible to considerably improve the usability of laser weapons by providing a laser weapon that can be operated by an individual infantryman and can shoot a high-power laser.
