COIL ELECTRONIC COMPONENT |
| 摘要 |
A coil electronic component includes a body having a coil part disposed therein and external electrodes connected to the coil part. The body includes a plurality of magnetic particles. In one example, a particle size distribution D50 of the magnetic particles in the body is 1 μm or less. In other examples, a particle size distribution D99 of the magnetic particles in the body is 1 μm or less; a particle size distribution ratio D99/D50 of the magnetic particles in the body is 1.5 or less; and/or a variation coefficient of the particle size of the magnetic particles in the body is 20% or less. |
