Non-directional electromagnetic steel sheets with excellent high frequency wave properties independently developed by JFE Steel Co., Ltd.
Super cores with silicon content of 6.5% which did not exist previously, were successfully introduced to the world. Low noise, low loss and high magnetic transparency can be realized.
They were used in various fields including high frequency reactors and energy efficient active filters, and more recently in high pressure circuits for hybrid cars, and these uses have been expanding. |

R Block cores
[Properties]
Because the block core angle is rounded and band stopping is possible, the same assembly time is possible.
There is no initial cost for molds etc. and length, width, laminate thickness and size can be freely set Mass production at low cost is possible.
Manufacturing is done with super E core as the material for high frequency low noise and super HF core as the material for high frequency and low core loss. |
