Abstract
A chip-type coil component capable of reducing the resistance of the coil while minimizing a decrease in the inductance of the coil includes magnetic layers composed of a multilayer body. The chip-type coil component further includes internal electrodes laminated on the magnetic layers. The internal electrodes are connected to each other to form a coil. The chip-type coil component further includes an auxiliary internal electrode laminated on each of the magnetic layers. Each auxiliary internal electrode is connected in parallel to the internal electrode laminated on the magnetic layer that is different from the magnetic layer on which the auxiliary internal electrode is laminated.
Claims9
A chip-type coil component, comprising:
- a multilayer body including a plurality of insulating layers;
- a plurality of internal electrodes laminated on the insulating layers and connected to each other to form a coil;
- and
- auxiliary internal electrodes laminated on the insulating layers on which the internal electrodes are laminated,
- wherein the auxiliary internal electrodes are provided on the insulating layers on which the internal electrodes are laminated, on a one-to-one basis,
- wherein each of the auxiliary internal electrodes is connected electrically in parallel to the internal electrode laminated on one of the insulating layers that is different from the insulating layer on which the auxiliary internal electrode is laminated, and
- wherein the auxiliary internal electrode and the internal electrode laminated on the same insulating layer are insulated from each other.
