Shield Yoke Sheet for Wireless Chargers FINEMET® MS Series

Processed laminated sheet using low-loss, high permeability nano-crystalline material FINEMET® helps reduce noise and energy loss of wireless electric power transmission and also magnetic shield yoke sheets for small electronic devices.

We propose a method to use materials tailored to your company.

MS-HiQ Series / FINEMET® Magnetic Shield Yoke Sheet for Wireless Charging

A magnetic sheet with a significantly improved Q value for shield yoke applications of wireless charging.

Features

  • Significantly improved Q value of our conventional MS series by controlling the magnetic permeability
  • Achieved high mechanical reliability with excellent flexibility and impact resistance
  • Superiority in the assembling process of the wireless charging system (forming and handling such as cutting, punching, etc.)
  • Achieved thinner and lighter sheet with the high saturation magnetic flux density of our FINEMET® sheet(1.23T, ref. Mn-Zn(ML29D) ferrite: 0.54T) (Using FINEMET® is 50% thinner and 35% lighter than with ML29D)
