Toda Kogyo is a chemical material manufacturer with nearly 200 years of experience as a manufacturer of iron oxide pigments.
As the leading manufacturer in the industry, we meet the diverse needs of customers throughout the world by utilizing the characteristics of inorganic materials to develop and supply a wide range or iron oxides and material parts.
FLX series is thin flexible ferrite sheets manufactured by soft magnetic Ni-Zn-Cu ferrite powder with optimized characteristics, and it is used for RFID tags and noise suppression generated from electronic devices and RFID tags. In addition, MBT series of ferrite IC tags is small and metal-compatible IC tags/NFC tags in the HF band developed by original ferrite materials, design and manufacturing technologies of Toda Kogyo which can be used for new applications that were not previously available by traditional IC tags.
Flexible Ferrite Sheet (FLX series)

The flexible ferrite sheet (FLX series) is sintered ferrite magnetic sheets with high magnetic permeability and low loss that applies soft ferrite technologies of Toda Kogyo.
- High µ’ & Low Loss
- By designing suitable materials for the application, it realizes magnetic properties of higher magnetic permeability μ’ and lower loss μ’’ than the conventional sheet and obtains excellent communication distance and charging efficiency.
- High Flexibility
- By dividing the ferrite into several mm pieces in advance and giving flexibility, we provide a magnetic sheet that does not degrade the characteristics and has good handling during mounting.
- Very Thin
- Because it possesses excellent magnetic properties, it can be thinned. This makes it ideal for wireless communication devices requiring lower profile, such as smartphones and compact communication devices.
Applications
Due to excellent magnetic flux dissipation, it is used for various applications in situations where thinning or miniaturization is required.
Example: RFID tags for metals, NFC tags, magnetic shields for wireless power, noise suppression sheet.
