What are Edgewise Coils?
Edgewise coil (EWC) is a general term for coils made from rectangular wire that are processed on the edge (short side) where it is less likely to bend.

Strengths of Maruho Hatsujyo Group
Design support
- Once you specify the characteristic value (inductance), we will propose the shape, material type, and material dimensions that match the characteristics.
- We have track records of post-processing evaluation (we have an LCR meter in-house) and delivery.
We will make suggestions that suit each product.
If you have any questions, please feel free to contact us.
