An apparatus has a laminate substrate that has a first surface and an opposite second surface. A laminate transformer is located within the laminate substrate between the first surface and the second surface. The transformer has a first coil adjacent the first surface and a second coil adjacent the second surface. A magnetic core element on the first surface overlaps a portion of the first coil. A lead frame on the first surface is spaced apart from the magnetic core element. A portion of the lead frame overlaps a portion of the first coil to provide a thermal conductive path.

A surface mount device inductor has a package casing sized to attenuate electromagnetic coupling between the inductor coils of the surface mount device inductors. The package casing makes the surface mount device inductors self-shielding. The surface mount device inductors can be incorporated into a radiofrequency module, and can be incorporated into a front end system of a wireless mobile device.

A coil component includes first and second wires wound around a winding core portion of a core, and third and fourth wires wound around outside a portion of the first and the second wires wound around the winding core portion in an opposite direction to a winding direction of the first and second wires. The portion of the first and second wires wound around the winding core portion has a first twisted wire portion twisted together. A length of the first wire or a length of the second wire of the portion of the first and second wires wound around the winding core portion is configured to be equal to a length of the third wire or a length of the fourth wire of the portion of the third and fourth wires wound around outside the portion of the first and second wires wound around the winding core portion.

An edge mount magnetic component includes a bobbin and two E-core halves. The bobbin is configured to receive the two E-core halves when body portions of the two E-core halves are positioned vertically. The bobbin includes a first outer flange, a second outer flange, and a passageway spanning therebetween. The bobbin further includes first, second, third, and fourth pin supports. The first and second pin supports are connected to an outer surface of the first end flange and are spaced apart by at least a width of the passageway. The third and fourth pin supports are connected to an outer surface of the second end flange and are spaced apart by at least the width of the passageway. The bobbin further includes slots for routing a winding to a pin and includes walls to ensure the winding is electrically separated from the E-core halves.

A highly reliable coil component having reduced electric resistance and improved bonding strength in a connection portion between a coil conductor and an external electrode. A coil component includes an element body including a coil conductor including a wound conductive wire coated with an insulating film, a magnetic portion containing metal magnetic particles and resin, and an external electrode on a surface of the element body and electrically connected to exposed surfaces, which are exposed on the surface of the element body, of extended portions of the coil conductor. The external electrode includes at least one or more layers. When an average crystal grain size of crystal grains constituting the coil conductor is defined as a and an average crystal grain size of crystal grains constituting a base electrode layer of the external electrode directly connected to the coil conductor is defined as b, a>b is satisfied.

An electronic component preventing peeling of an external terminal is provided. Since each of the external terminal electrodes on the upper face has a U-shaped outline, stress concentration is less likely to occur at an inner end portion than in the external terminal electrode having a corner at the inner end portion. Therefore, for example, even when an impact is applied, a situation in which the external terminal electrode peels off from the upper face due to stress concentration is prevented.

An inductor array includes a magnetic base body having first and second surfaces opposed to each other and a third surface connecting between the first and second surfaces, and also includes first and second end internal conductors having the same shape. The first end internal conductor includes first-end first conductor portions and fewer first-end second conductor portions, alternating with and being connected to each other. The second end internal conductor includes second-end first conductor portions and fewer second-end second conductor portions, alternating with and being connected to each other. The first-end first conductor portions are positioned away from the first surface by a first end distance in a reference axis direction and face the first surface. The second-end second conductor portions are positioned away from the second surface by a second end distance less than the first end distance in the reference axis direction and face the second surface.

A coil component includes: a body; a coil portion including a coil pattern disposed in the body and first and second lead portions exposed to a first surface of the body to be spaced apart from each other; and first and second external electrodes disposed on the first surface of the body and spaced apart from each other and connected to the first and second lead portions, respectively, wherein in a cross-section perpendicular to the first surface of the body, a curved portion having a radius of curvature of 1 μm or more is formed in a region in which each of the first and second lead portions and an outermost turn of the coil pattern are connected to each other.

A coil component includes: a body; a coil unit including lead-out ends and coils, and embedded in the body; and a core penetrating through the coil unit in a first direction, wherein a cross-section of each of the coils perpendicular to a direction in which the coil is wound has a plurality of round portions disposed on a side facing the core.

A coil component includes a body; an insulating substrate embedded in the body; and a coil portion disposed on at least one surface of the insulating substrate. The insulating substrate is inclined with respect to one surface of the body, in a cross-section of the body in a width-thickness direction.
