Title:
RESIN CONTAINING MAGNETITE AND ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2012/032930
Kind Code:
A1
Abstract:
Provided is a resin containing a magnetic substance for coatings and forming cores which makes obtaining a coil with a large Q value and superior direct current superimposition characteristics possible.
This resin containing magnetite contains magnetite having remanent magnetic flux density of less than 15 Am2/kg and coercive field strength of less than 12 kA/m. Furthermore, a coil (100) according to the present invention is made from a structure in which the windings (2) are coated with the resin containing magnetite and a magnetite-containing resin layer (5) is formed.
