Definitions
- the present invention is applicable to a frequency band from several KHz to several tens of MHz by automatic molding at a high temperature of 200 to 550 ° C., which has not been possible in the prior art, and has a high permeability amorphous green powder core core having a high permeability of 75% or more. And a method for producing the same.
- the permeability is not high is that the molding density is only about 70% of the true density, and one way to solve this problem is to increase the molding temperature.
- a conventional lubricant cannot be used as a precondition, and a lubricant that can withstand high temperatures is required, and an improvement in insulation properties is required as the compression density by molding is increased.
- Another object of the present invention according to the manufacturing method, high molding density, no surface crack, good inter-particle insulation, low frequency dependence, high permeability by high temperature molding with a small variation in the effective permeability even in high frequency band To provide amorphous green cores.
- the molding may be performed at a pressure of 10 to 25 ton / cm 2 in a temperature section of 200 to 550 ° C., and the heat treatment of the core may be performed at a temperature of 400 to 600 ° C.
