| 摘要 |
<p>A high frequency power inductance element capable of remarkably reducing a leakage by remarkably reducing an interwinding capacity, remarkably increasing a heat radiation from coils, and remarkably improving a productivity and a cost, comprising coils (L1, L2) formed of a band-shaped conductor (10) spirally wound in a cylindrical shape so that the wider surfaces thereof come flush with each other, an electrically insulated bobbin (2) for installing the coils (L1, L2) thereon, and cores (31, 32) inserted into the bobbin (2) to form a closed magnetic circuit.</p> |
