Abstract

Patente de Invenção: <B>"ESTRUTURA DE NúCLEO E DE BOBINA E MéTODO PARA FABRICAR A MESMA"<D>. Um dispositivo indutivo é compreendido de uma pluralidade de pastilhas dielétricas (100) possuindo padrões condutivos (126) dispostos nas mesmas e sendo formado dentro de uma estrutura de laminado. A estrutura de laminado inclui um núcleo ferromagnético (124) encaixotado dentro do material dielétrico (104). Os padrões condutivos (126) estão interconectados utilizando vias (122) para criar uma estrutura condutiva, tal como enrolamentos, ao redor do núcleo. Durante a fabricação do dispositivo, o núcleo é pressurizado para manter as características de alta permeabilidade. Como um resultado, os dispositivos indutivos tal como tansformadores e indutores podem ser feitos possuindo dimensões pequenas e altos valores indutivos.
