Zusammenfassung: | To develop a common-mode noise filter for balanced-mode digital signal interfaces such as USB ver. 2 and IEEE 1394, a Mn-Zn ferrite/Polyimide composite thick film was fabricated and applied to the filter device. The polycrystalline Mn-Zn ferrite powder and polyimide precursor liquid solution were used as the starting materials for the composite thick film. The composite film had a large imaginary part of complex permeability at high frequencies over 1GHz, and high permittivity. The common-mode noise filter using the composite film exhibited the common-mode suppression of over 10dB in the frequency range over 1GHz. |
