Title
(EN) INDUCTOR WITH THERMALLY STABLE RESISTANCE
(JA) 熱的に安定な抵抗をもつインダクター
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an inductor having winding resistance with improved temperature stability.

SOLUTION: An inductor 10 includes an inductor body 12 having a top surface 14 and first and second end surfaces 18, 20 facing each other. There is a void 28 through the inductor body between the first and second end surfaces. A thermally stable resistive element 30 is positioned through the void and turned toward the top surface to form surface mount terminals 32, 34, 38, 40. When the inductor body is formed of a ferrite, the inductor body includes a slot 26. The inductor may be formed of a distributed gap magnetic material formed around the resistive element. The inductor body 12 is positioned around the thermally stable resistive element such that terminals of the thermally stable resistive element extend from the inductor body.

【課題】温度安定性が改善された巻き線抵抗をもつインダクターを提供する。
【解決手段】上面14、および対向する第1端面18および第2端面20を有するインダクター本体12からなるインダクター10であり、対向する第1端面および第2端面の間においてインダクター本体に中空部分28を設け、この中空部分に熱安定性抵抗要素30を配置し、上面に向けて折り曲げ、表面実装端子32、34、38、40を形成する。インダクター本体をフェライトで構成する場合、インダクター本体にスロット26を形成する。インダクターは、抵抗要素の周りに形成した分布型ギャップ磁性材料から構成することができる。また、熱安定性抵抗要素の周りにインダクター本体12を配置し、熱安定性抵抗要素の端子をインダクター本体から延設する。
