Processing and Feature
Multilayer
Multilayer
Suitable for product miniaturization. Products have been made available for both high frequency applications and power circuit applications by using different core materials.
Wire Wound
Wire Wound
Thick copper wire is used to reduce DC resistance, making the inductors suitable for large current applications.
Thin-film
Thin-film
The combination of high precision patterns and material with outstanding magnetism make the inductors suitable for miniature and thin-profile applications and where the ability to handle large volumes of current is required.
Laser Cut
Laser Cut Winding
Laser cut is a precise and reliable process for production of robust components with excellent RF characteristics and high resonance frequencies.
Shield
Magnetic Shield
Coil parts are covered by a magnetic material to reduce leakage of magnetic flux, making the inductors suitable for high-density packaging.
No Directivity
No Directivity
Almost no changes in characteristics due to the winding direction of the coil.
Metal Core
Metal Core
Little inductance change is experienced due to temperature and harder-to-reach magnetic saturation compared to ferrite, which causes rated current Idc1 (current value based on inductance change) to become large.
Ferrite Core
Ferrite Core
Exhibit stable characteristics up to the magnetic saturation point, due to the flat DC bias characteristics.
Non-Mag Core
Non-Magnetic Core (Dielectric Ceramic)
Experiences almost no inductance drop due to currents and exhibits stable temperature characteristics, since the magnetic saturation characteristics are not a concern with a non-magnetic material.
Soft
Soft Termination
Inductors with resin terminal electrode layer
A²B
A²B
Inductors for automotive A²B (Audiobus).
AEC-Q200
AEC-Q200
Shows whether the product has undergone evaluation tests based on the AEC-Q200, which is a test standard for automotive passive components set by the AEC of the United States. Please contact us for details concerning concrete evaluation testing methods and their results.
