JFE Super Core Products

 
  • The base coil is made on a continuous production line with a siliconizing process.
  • The base coil goes through a slitter line, slits are cut and the coil is hooped.
  • After a paper sleeve is put around its inner circumference, the slit coil is wound with rust-preventing paper used for packaging. It is then placed on skids for shipment.
[Insulating Coating]
A mixture of organic and inorganic type of coating is available.

* W10/50 indicates the core loss at 50 Hz, 1 T (=10kG) when the magnetic flux sine wave is excited. Similarly, W10/400 indicates for 400 Hz, 1 T (=10kG), and W0.5/20k indicates the core loss for 20 kHz, 0.05 T (=500G).
