Abstract

UN APARATO DE FILTRO DE PERDIDAS REDUCIDAS PARA SUPRIMIR INTERFERENCIA DE RADIOFRECUENCIA EN UNA LINEA BIFILAR. EL APARATO INCLUYE UNA UNIDAD DE BOBINA (10) QUE COMPRENDE DOS BOBINAS (POR EJEMPLO, 3A) EN FORMA DE CIRCUITOS IMPRESOS A AMBOS LADOS DE UNA PLACA AISLANTE (2), UNA ENVOLVENTE DE FERRITA (10A, 10B) QUE RODEA LA UNIDAD DE BOBINA (1), EXISTIENDO TAMBIEN DOS CONDENSADORES (15A, 17A, 15B, 17B), CUYOS REVESTIMIENTOS ESTAN SITUADOS AL MENOS PRACTICAMENTE PARALELOS A LA PLACA AISLANTE (2) EN DOS SUPERFICIES DE LOS ELEMENTOS DE FERRITA QUE MIRAN EN SENTIDOS OPUESTOS Y QUE MIRAN HACIA AFUERA DE LA UNIDAD DE BOBINA (1). EL REVESTIMIENTO (15A, 15B) SITUADO MAS CERCA DE LA UNIDAD DE BOBINA (1) EN CADA CONDENSADOR ESTA PROVISTO DE UN TERMINAL DE TIERRA (POR EJEMPLO, 16A) Y EL OTRO REVESTIMIENTO (17A, 17B) EN CADA CONDENSADOR ESTA CONECTADO AL PUNTO DE EXTREMIDAD INTERIOR DE LA BOBINA (POR EJEMPLO, 3A) SITUADO MAS CERCA DEL REVESTIMIENTO.
