ISOLATOR

摘要

PURPOSE: An isolator is provided to improve the quality thereof by placing a chip resistive device and three dielectric devices on an exterior substrate of a lower case. CONSTITUTION: An isolator includes an upper case(110) and a lower case(180). A magnetic body(120) is positioned in the lower case(180) to generate a magnetic field according to an input current. An inner terminal is positioned under the magnetic body, and has a strip line which is connected with input and output terminals. The isolator further includes a chip resistor and three dielectric devices(150a-150c). The chip resistor, three dielectric devices(150a-150c) and input and output terminals are formed at an upper side of an exterior substrate(190) of the lower case(180). The upper and lower cases(110 and 180) are of cylindrical shape. The upper and lower cases(110 and 180) have a hole to allow the strip line to be connected with an exterior.
