ABSTRACT:
A nonreciprocal circuit element of the present invention comprises a first yoke and a second yoke that form a magnetic closed circuit. A plurality of chip capacitors with a first electrode and a second electrode are installed in the box-shaped second yoke. Subsequently, a circuit substrate used for the nonreciprocal circuit element can be smaller than conventional circuit substrates, and the assembly of the nonreciprocal circuit element is excellent. Further, since the capacitances of the chip capacitors can be adjusted through windows of the second yoke, the electrical performance of the nonreciprocal circuit element is excellent.
