Features
| Process | Wire Wound | These products have a structure consisting of a core with copper wires wound around it. The use of thick copper wires can reduce the DC resistance, making them suitable for applications with large currents. Composite-type products (SPM series), whose wire wound coils are integrally molded using magnetic metal powder, are also available, and are effective in countermeasures against coil acoustic noise. |
|---|---|---|
| Multi Layer | Metal conductors are printed on sheets which are then laminated to create coils. These products are well-suited to achieving smaller product sizes and lower profiles, with excellent mass-producibility. | |
| Thin Film | Thin film processing is employed to make high-density pattern forming possible. Combinations with metallic magnetic materials make these products suitable for applications requiring small sizes and low profiles, as well as large currents. | |
| Magnetic Material | Ferrite | These products have high μ and are suitable for high-inductance applications. They also possess consistent DC superimposition characteristics, demonstrating stable properties up to the magnetic saturation point. |
| Metal | Since these products have small changes in inductance depending on temperature, and are less likely to experience magnetic saturation than ferrite, they possess soft saturation characteristics. | |
| Shield Type | No Shield | A simple, open magnetic circuit type with no magnetic shielding on the coil components. |
| Resin Shield | The areas around the coil are covered with resin which contains a mixture of magnetic powder such as ferrite and soft magnetic metals. Compared to shielded types, the magnetic shielding effectiveness of these products is limited, but they have good cost balance. | |
| Shield | Covering the areas around the coil with a shield core and molding with magnetic materials gives these products a structure similar to a closed magnetic circuit. This type has high magnetic shielding effectiveness with lower magnetic flux leakage than all other types. |
