Abstract
A coil component includes a wound coil having a winding portion, having at least one turn, and a lead-out portion extending from an end portion of the winding portion to provide a separation space together with the winding portion and a body including an insulating resin and magnetic powder particles and embedding the wound coil therein. The body has a low-density portion disposed in the separation space and having magnetic powder particle density lower than average magnetic powder particle density of an entirety of the body.
Claims17
A coil component comprising:
- a wound coil having a winding portion, having at least one turn, and a lead-out portion extending from an end portion of the winding portion at a contact point to provide a separation space together with the winding portion;
- and
- a body including an insulating resin and magnetic powder particles and embedding the wound coil therein,
- wherein the body has a low-density portion disposed in the separation space and having magnetic powder particle density lower than average magnetic powder particle density of an entirety of the body, and
- wherein the low-density portion extends from the contact point.
A coil component comprising:
- a body including an insulating resin and magnetic powder particles;
- and
- a wound coil having a winding portion and a lead-out portion extending from an end portion of the winding portion at a contact point to be spaced apart from the winding portion, and embedded in the body,
- wherein the body comprises:
- a low-density portion covering a surface of the wound coil having a separation space between the winding portion and the lead-out portion;
- and
- a high-density portion disposed outside of the low-density portion and having higher density of the magnetic powder particles than the low-density portion, and
- wherein the low-density portion extends from the contact point.
A coil component comprising:
- a wound coil having a winding portion, having at least one turn, and a lead-out portion extending from an end portion of the winding portion at a contact point to provide a separation space together with the winding portion;
- and
- a body including a first insulating resin and magnetic powder particles and embedding the wound coil therein,
- wherein the body further includes a second insulating resin disposed in the separation space and having a melting point lower than a curing temperature of the first insulating resin, and
- wherein the second insulating resin extends from the contact point.
