METHOD FOR PRODUCING MnZn FERRITE CORE
PROBLEM TO BE SOLVED: To produce a core used for a choke coil easily and economically under high productivity, a noise attenuation function of which does not deteriorate and one of which is enough to cover a prescribed frequency band in a wide temperature range from a low temperature of -20°C including room temperature to a high temperature of 120°C to 150°C.SOLUTION: Provided is a method for producing a MnZn ferrite core, which acquires an integrated structure by piling a plurality of divided cores which are divided parallel to a magnetic path. As a material of the divided cores, molded bodies comprising MnZn ferrite having material qualities of different magnetic characteristics are prepared, and the prepared molded bodies are piled without inserting a releasing agent between the piled bodies and calcined.SELECTED DRAWING: Figure 1
【課題】室温を含む−２０℃の低温から１２０℃〜１５０℃の高温までの広い温度域で、ノイズ減衰機能が低下せず、かつ１個で所定の周波数帯域をカバーできるチョークコイルに使用されるコアを、高い生産性の下、容易かつ低コストに製造する。【解決手段】磁路に平行に分割された複数個の分割コアを重ね合わせて一体化した構造になる、ＭｎＺｎフェライトコアの製造方法において、分割コアの素材として、磁気特性が異なる材質のＭｎＺｎフェライトからなる成形体を準備し、準備した成形体を、その間に剥離剤を挿入することなく重ね合わせ、焼成することにより一体化する。【選択図】図１
