Main magnetic characteristics examples
Complex relative permeability


Product with a thickness of 10μm is the most suitable for high-frequency applications. However, it is also possible to increase the magnetic shielding effect by the foil thickness, so the thickness can be selected according to the intensity of the adaptive magnetic field.

Applicable frequency band of permalloy foil material
STARPAS®-PC2S is suitable for high-sensitivity applications.

Magnetic shield performance at high frequencies
It shows a high shield property unlike aluminum (non-magnetic) at 1MHz. It also functions as an electromagnetic wave shield even at high frequencies.

We provide the magnetic shield and yoke material in 50 kHz ~ 10MHz band.
STARPAS®-PC2S is suitable for strong magnetic field applications.

Magnetic shield performance depending on magnetic field strength
STARPAS®-PC2S shows high shield performance in a weak magnetic field. STARPAS®-DF42N maintains high shield performance in strong magnetic field.

We provide highly efficient magnetic yoke materials (Sheet for wireless power supply)

Easy-to-handle material performance
Our materials are so flexible with excellent processability that your applications are expanded.

Lineup of products with tape and laminate
We have a lineup of adhesive tapes and laminated products on high-frequency sheet metal foil (metal foil) to improve usability.
