● It is higher permeability magnetic sheet which is suitable for magnetic shield and improving

performance of wireless charging system according to international standard around 100kHz

such as Qi standard.

● S

intered ferrite material with flexibility enables higher drop impact resistance.

● Suitable for thinner design of module. (Total thickness of product: 0.21mm)

● C

ustom profile is available upon request.
