Abstract

An electrical component is disclosed. The electrical component includes a current conducting coil having inside and outside surface and terminal ends that are configured for connection to an electrical circuit and compressed iron particles that form a body which completely contacts the inside and outside surfaces of the coil for magnetically shielding the coil and leaving the terminal ends exposed for connection to the electrical circuit.

Claims

1. An electrical component comprising:

a current conducting coil having inside and outside surface and terminal ends that are configured for connection to an electrical circuit; and

,

compressed iron particles that form a body which completely contacts the inside and outside surfaces of the coil for magnetically shielding the coil and leaving the terminal ends exposed for connection to the electrical circuit.

2. An electrical component comprising:

a current conducting coil having inside and outside surface and terminal ends that are configured for connection to an electrical circuit; and

,

compressed iron particles that form a body which completely contacts the inside and outside surfaces of the coil that magnetically shields the coil and leaves the terminal ends exposed outside the body.

3. An electrical component comprising:

a current conducting coil having inside and outside surface and terminal ends that are configured for connection to an electrical circuit; and

,

compressed iron particles that form a body which completely contacts the inside and outside surfaces of the coil,

whereby the terminal ends are exposed outside of the body and the coil is magnetically shielded.

4. An electrical component comprising:

a current conducting coil having inside and outside surface and terminal ends that are configured for connection to an electrical circuit; and

, compressed iron particles that form a body which completely contacts the inside and outside surfaces of the coil and enhances induction and efficiency of the coil.
