Abstract
Official abstract text for this publication.
A dust core includes magnetic particles, an epoxy resin, and an additive. The epoxy resin has at least two or more mesogenic skeletons between two epoxy bonds adjacent along a molecular chain. The additive includes one or more metallic elements selected from Li, Ba, Mg, and Ca.
First claim
Opening claim text (preview).
What is claimed is: 1 . A dust core comprising magnetic particles, an epoxy resin, and an additive, wherein the epoxy resin has at least two or more mesogenic skeletons between two epoxy bonds adjacent along a molecular chain, and the additive includes one or more metallic elements selected from Li, Ba, Mg, and Ca. 2 . The dust core according to claim 1 , wherein the additive includes Li, and a weight ratio of Li to a total weight of the magnetic particles, the epoxy resin, and the additive is 10 ppm or more and 100 ppm or less. 3 . The dust core according to claim 1 , wherein the additive includes Ba, and a weight ratio of Ba to a total weight of the magnetic particles, the epoxy resin, and the additive is 190 ppm or more and 600 ppm or less. 4 . The dust core according to claim 1 , wherein the additive includes Mg, and a weight ratio of Mg to a total weight of the magnetic particles, the epoxy resin, and the additive is 30 ppm or more and 130 ppm or less. 5 . The dust core according to claim 1 , wherein the additive includes Ca, and a weight ratio of Ca to a total weight of the magnetic particles, the epoxy resin, and the additive is 60 ppm or more and 200 ppm or less. 6 . The dust core according to claim 1 , wherein the magnetic particles comprise soft magnetic metal particles each including Fe as a main component. 7 . An electronic device comprising the dust core according to claim 1 .
