LUMPED CONSTANT TYPE ISOLATOR

摘要

PURPOSE: A lumped constant type isolator is provided to maximize the sizes of a dielectric material and a chip resistor by removing outer walls mounted in the interior side of an injection case of an isolator. CONSTITUTION: A ferromagnetic material(32) generates a static magnetic field by an input current. An internal terminal part(33) is located on the lower side of the ferromagnetic material(32) and connected to input and output terminals and a ground terminal together with a garnet ferrite(41). A chip resistor(34) and three dielectric devices(35a-35c) are connected to three terminals of the internal terminal part(33). Partitions(44, 44') are protruded in a certain height. The partitions(44, 44') are mounted before and after a ferrite connection hole of an injection case(36) in which the garnet ferrite(41) is built in.
