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)
Characteristics
- *Our evaluation value by ring core
Measurement conditions: f = 85kHz, V = 0.03V
