## Abstract

An inductor includes a core, a plate that holds the core, and a flat copper wire wound around the core in a single layer. The flat copper wire is coated with potting.

## Claims

### Claim 1

An inductor comprising:
a core;
a plate that holds the core; and
a flat copper wire wound around the core in a single layer; wherein
the flat copper wire is coated with potting.

### Claim 2 (depends on 1)

The inductor of claim 1, wherein the potting is silicon.

### Claim 3 (depends on 1)

The inductor of claim 1, wherein
the plate includes two plates on each side of the core,
each of the two plates is L-shaped with a shorter side extending toward the core, and
the shorter sides of the two plates each include a mounting feature to mount the inductor to a substrate.

### Claim 4 (depends on 1)

The inductor of claim 1, wherein the core includes an amorphous metal or a high-silicon steel.

### Claim 5 (depends on 1)

The inductor of claim 1, wherein the core has a CC construction with a center.

### Claim 6 (depends on 5)

The inductor of claim 5, wherein the center is potted with a silicon potting.

### Claim 7 (depends on 1)

The inductor of claim 1, wherein the flat copper wire includes a tapped terminal.
