Application field:
Fe-based nanocrystalline cores can replace permalloy, and can be applied to electronic or
electromagnetic products.Well used in current transformers,high instrument transformers and high precious transformers etc.
Performance characteristics:
Beneficial to diminishing theaction current of leakage switch and improving accuracy with high
permeability and low loss; long-term work stability with excellent capacity of antioverload;
10% out rate of change between -10 to 80 .
After special solidification surface treatment, minor effect of pressure on the wound cores.
