Nanocrystal Cores

The nanocrystal core is an alloy core made by turning an alloy into a ribbon shape, cutting into appropriate width, and rolling as if to wind a tape.
The nanocrystal core has excellent permeability (35,000~80,000) and can be designed to have a smaller size than the conventional ferrite cores. This core is primarily used in noise filters and current transformers.

Applications

Switched-mode Power Supplies
Uninterruptible Power Systems
Pulsed welding equipment
Power inverter
Wind generators
Frequency Converter
