1. Introducción del producto Inductor CDRRI
Detalles de producción: el inductor CDRRI es una mejora de las funciones básicas de los inductores en forma de I. Para proteger los cables, bucles y bobinas del campo magnético externo y debilitar el efecto de interferencia del campo electromagnético generado por el circuito en otros componentes, se utilizan materiales magnéticos. Un modo de inductancia para blindaje, cuya función principal es reducir la interferencia de la inductancia al mundo exterior.
