Title:
INDUCTOR FOR CURRENT-LIMITING CIRCUIT
Document Type and Number:
Japanese Patent JP2016225590
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an inductor for current-limiting circuit, capable of retaining a large inductance at instantaneous large current conduction for exhibiting a current-limiting effect even with a small size, particularly used for an electric current requiring no inductance at normal operation.SOLUTION: An inductor 1 for current-limiting circuit includes a magnetic core 2 and a coil 3 and is used for a current-limiting circuit, particularly used for a soft magnetic material with a low volume resistivity and a high magnetic permeability in at least a part of the magnetic core 2. The soft magnetic material is, for example, sinter pure iron.SELECTED DRAWING: Figure 1
