Abstract: A reactor is composed of a coil and a core placed in the inside area and outer peripheral area of the coil in a container. The core is composed of magnetic powder, non-magnetic powder, and resin. The non-magnetic powder is composed of main component powder and low elastic modulus powder. The main component powder as a main component of the non-magnetic powder is made of one or more kinds of powder of a heat conductivity which is larger than that of the resin. The low elastic modulus powder is made of one or more kinds of powder of an elastic modulus which is smaller than that of the powder forming the main component powder.

Abstract: A magnetic core is obtained by hardening or curing a mixture of magnetic powder and resin. The magnetic core shows a superior DC bias characteristic which does not become drastically saturated but is gently saturated even beyond 1000*103/4π [A/m]. Therefore, the magnetic core has sufficient relative permeability more than ten.

Abstract: A method of fabricating a reactor composed of a coil, a core, and a container, capable of suppressing the core to break when a current flows in the coil to generate magnetic flux. In the method, the coil is formed by spirally winding a conductive wire. The coil is immersed in an insulating film in liquid with electrical insulation. The coil is placed in a furnace. Annealing for the coil and thermosetting for the insulating film are performed at a temperature within 250 to 320° C. for a period of time within 30 minutes to one hour before forming the core in the container. The coil is then disposed in the container. Inside and outside areas of the coil in the container is filled with a resin mixture composed of magnetic powder and resin. The resin mixture in the container is hardened to form the core.
