Patent ID: 6906597

Claim:
A resin casing used in a non-reciprocal circuit device comprising an assembly of a ferrimagnetic body and a plurality of central conductors enclosing said ferrimagnetic body, and a plurality of elongated flat capacitors connected to ends of said central conductors; said resin casing comprising a conductor plate constituting a magnetic yoke for said non-reciprocal circuit device and having a substantially flat bottom surface, and a resin frame injection-molded integrally with said conductor plate; said resin frame having sidewalls and partition walls inside said sidewalls for defining a plurality of recesses for receiving said flat capacitors; a pair of opposing sidewalls being provided with external terminals constituted by said conductor plate; any bottoms of a plurality of said recesses being integrally formed by a substantially flat bottom portion of said conductor plate; said recesses being formed such that said recesses receive all of said flat capacitors, each of said flat capacitors having a first side and a second side, said first side having a length greater than a length of said second side, all of said flat capacitors being arranged in said recesses such that said first side of each of said flat capacitors is substantially in parallel with sidewalls having said external terminals; and said assembly being disposed on said flat capacitors received in said recesses.
