Ferrites sheets for EMI suppression
 |
Operation errors of an electronic device are often caused by EMI noise
from another electronic device nearby. Also, exising EMI control products
are ineffective to high-frequency digital equipment as well. Utilizing
original material and processing technologies, FDK has developed new EMI
suppression sheets abreast with the advancement of electronics. |
