Abstract
An inductor and method for making the same are provided. The inductor includes a coil formed from a conductor and having a serpentine shape. The coil may have an “S”-shape. The coil has two leads extending from opposite ends of the coil. An inductor body surrounds the coil and portions of the leads. The leads may be wrapped around the body to create contact points on the exterior of the inductor.
Claims16
An inductor comprising:
- a single serpentine first coil and formed from a flat continuous piece of conductive metal, the coil comprising:
- a first portion having a first end adjacent a first side of the inductor and a second end extending away from the first side of the inductor,
- a third portion having a first end adjacent a second side of the inductor and a second end extending away from the second side of the inductor, the first side of the inductor and the second side of the inductor on opposite sides of the inductor,
- at least a part of an inner side of the first portion facing at least a part of an inner side of the third portion and forming a space between the first portion and the third portion, and
- a second portion connecting the second end of the first portion and the second end of the third portion, the second portion traversing the space between the first portion and the third portion, wherein the second portion connects to the first portion at a first position and wherein the second portion connects to the third portion at a second position, and wherein the first position is closer to the second side of the inductor than the second position;
- a first lead extending from the first end of the first portion of the coil;
- a second lead extending from the first end of the third portion of the coil;
- and
- a body comprising a pressed magnetic powder pressed around the coil and portions of the first lead and the second lead;
- wherein the first portion curves outwardly toward a third side of the inductor, and wherein the third portion curves outwardly toward a fourth side of the inductor, the third side of the inductor and the fourth side of the inductor on opposite sides of the inductor.

An inductor having a first side and a second side opposite the first side, a third side and a fourth side opposite the third side, comprising:
- a single serpentine first coil and formed from a flat continuous piece of conductive metal, the coil comprising:
- a first portion having a first end adjacent the first side of the inductor and a second end extending toward the second side of the inductor, the second end of the first portion positioned closer to the second side of the inductor than the first end of the first portion,
- a second portion having a first end connected to the second end of the first portion adjacent the second side of the inductor and a second end extending toward the first side of the inductor, the second end of the second portion positioned closer to the first side of the inductor than the first end of the second portion;
- a third portion having a first end adjacent the second side of the inductor and a second end extending toward the first side of the inductor, the second end of the third portion connected to the second end of the second portion adjacent the first side of the inductor, the second end of the third portion positioned closer to the first side of the inductor than the first end of the third portion,
- at least a part of an inner side of the first portion facing at least a part of an inner side of the third portion and forming a space between the first portion and the third portion, the second portion traversing the space, and
- a first lead extending from the first end of the first portion of the coil;
- a second lead extending from the first end of the third portion of the coil;
- and
- a body comprising a pressed magnetic powder pressed around the coil and portions of the first lead and the second lead;
- wherein the first portion curves outwardly toward the third side of the inductor, and wherein the third portion curves outwardly toward the fourth side of the inductor.
