New 3C97T Ferrite Material for Wireless Charging of Electric Vehicles (WPT)
New 3C97T Ferrite Material for Wireless Charging of Electric Vehicles (WPT)
Ferroxcube expands its ferrite core material range with the launch of the new 3C97T, a MnZn compound specifically engineered for wireless power transfer (WPT) applications in electric vehicles (EVs). This new material is designed to deliver ultra-low losses at 85 kHz — the standard frequency set by the SAE J2954 protocol — while maintaining stable performance up to 200 kHz. This makes it a versatile solution capable of supporting multiple charging protocols across different markets.
Optimized performance for real-world environments
Unlike other characterizations based on standard toroids, Ferroxcube has evaluated the 3C97T using toroidal cores machined from ferrite slabs, providing a more accurate representation of the material’s behavior in real wireless charging applications.
Although these tests may report slightly higher loss values than those obtained with ideal cores, the benefit lies in the reliability of the data for the final system design, minimizing the gap between simulation results and the actual product performance.
New datasheet format: more visual, more functional
With the launch of the 3C97T, Ferroxcube also introduces a new datasheet template that significantly enhances the reading experience by featuring:
- More intuitive loss vs. frequency diagrams
- Enhanced permeability and resistivity charts
- Clear layout of key parameters
This new approach makes it easier for technical staff to quickly interpret performance indicators, reducing evaluation time during the early stages of material selection.
Standard ferrite slab range for WPT
The 3C97T is available in a wide range of standard ferrite slabs, with surface areas up to 130 × 130 mm and thicknesses of 5 or 10 mm, meeting the most common enclosure requirements for charging pads. In addition, two optional edge finishes are offered:
- Unground edges: a more cost-effective option for designs with less demanding EMI control requirements.
- Rectified edges: reduces the gap between slabs, resulting in improved electromagnetic shielding and enhanced coupling efficiency.
This range of options allows for easy integration into most inductive charging systems, both in onboard (vehicle) applications and in base stations.
Customized solutions upon request
If your project requires specific parameters, Ferroxcube also offers customized solutions:
- Alternative thickness adjustments to optimize the balance between magnetic performance and thermal dissipation.
- Precision grinding on critical dimensions to meet strict mechanical tolerances.
- Special designs using dedicated tooling, which may include customized geometries for enclosure systems, cable routing holes, chamfers, rounded corners, or other complex shapes.
These customization options allow the 3C97T to be adapted to virtually any scenario, ensuring compatibility with complex WPT system architectures.
