Abstract
A multilayer chip bead includes: a body including a coil portion and cover layers disposed on upper and lower surfaces of the coil portion; first and second external electrodes disposed on external surfaces of the body; and a coil disposed in the coil portion, including coil patterns having a spiral shape and lead patterns, and having both end portions connected to the first and second external electrodes, respectively, through the lead patterns. A width of the lead pattern is smaller than that of the coil pattern.
Claims7
A multilayer chip bead comprising:
- a body including a coil portion and cover layers disposed on upper and lower surfaces of the coil portion;
- a coil disposed in the coil portion, the coil including coil patterns having a spiral shape and first and second lead patterns, the coil patterns being disposed on magnetic layers, respectively, and the magnetic layers being stacked in a stacking direction;
- and
- first and second external electrodes respectively disposed on external surfaces of the body opposing each other in a length direction perpendicular to the stacking direction,
- wherein the first and second lead patterns extend in the length direction, and are exposed from the external surfaces, respectively,
- the coil patterns include a first coil pattern disposed on a first magnetic layer of the magnetic layers, on which the first lead portion is disposed,
- the first coil pattern includes one section extending in the length direction, and an end of the one section of the first coil pattern is connected to the first lead portion by a first curved coil pattern on the first magnetic layer,
- the coil patterns include a second coil pattern disposed on a second magnetic layer of the magnetic layers, on which the second lead portion is disposed,
- the second coil pattern includes one section extending in the length direction, and an end of the one section of the second coil pattern is connected to the second lead portion by a second curved coil pattern on the second magnetic layer, and
- a width of each of the first and second lead patterns is smaller than that of each of the coil patterns.
