Thin-film coil

b
Structural superiority/ Electrical characteristics
Environmental conditions
Small thin-film coil (reduced stray capacity) with a high-
definition pattern design where the aspect ratio is made
as close to one as possible.
Application of high saturation magnetic flux density/high-
frequency low-loss ferrite material
Our approaches
Common-mode resonance frequency is shifted to a high
frequency range
Significant improvement of the high-frequency differen-
tial transmission characteristic
Achieved characteristic superiority
Thin-film coil with wide interfacial area
Ferrite material of conventional characteristic
Limitations of high-speed differential transmission due to
the stray capacity between coils
Downsizing and thinning is difficult for ferrite material
because of its characteristic limitations
Limitations in responding to the latest needs
