Non-Oriented Electrical Steel Sheet Super Core™
●Super Core™ is the highest grade, one-of-a-kind non-oriented electrical steel sheet product made by JFE Steel.
●With high saturation magnetic flux density and low iron loss in the high-frequency range, Super Core™ is a well-balanced product.
●Typical applications: high-frequency reactors, high-frequency transformers, magnetic shields, motors, etc.
Comparison of Magnetic Properties of Core Materials for High-frequency Reactors
Types of JFE Super Core™
A 6.5% silicon steel sheet with uniform silicon content throughout the sheet. JNEX CORE is ideal for low core loss and low noise (zero magnetostriction) needs in the high-frequency range.
A silicon steel sheet with 6.5% silicon content only in the surface layer. JNHF CORE exhibits even lower core loss than JNEX CORE for the high-frequency in excess of 5kHz.
