Applications
Nanocrystalline bead core for noise suppressor for semiconductor components (e.g. Mosfet)
> IGBT Driver transformer
> Current transformer
> High Frequency Power transformer
> ISDN Network transformer
> EMI/EMC Filter Common mode choke
> HD camera signal transformer
Characteristics:
>Small size – Reducing volume of component
– Reducing copper wires
– Reducing cost
> Size can be custom made — Help customers quick design and mold cost free
> High insulation strength – Withstand voltage meets 1000V requirement
> High permeability — Much higher inductance value than ferrite core
