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.
For frequency bands below 150kHz, PC2S products with thicknesses of 50μm and 30μm for high sensitivity are recommended.
