Shield Yoke Sheet for Wireless Chargers FINEMET® MS Series
Overview
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)
