The low core loss characteristics at high-frequency of Super Core? allow it to be effectively used for a wide range of transformers, driven from several hundred Hz to several tens of kHz. Super Core? allow the transformer to generate less heat, and provide higher design induction than conventional silicon steel sheets, enabling transformer size to be reduced. This then reduces the quantities of other required transformer materials, such as the copper wire, leading to overall cost reductions. By taking full advantage of the low magnetostriction characteristics of JNEX CORE??, it is also possible to reduce transformer noise dramatically.

Due to the high saturation magnetic flux density, the low core loss at high-frequency and the high-permeability of Super Core? , it is ideal for applications in high-frequency reactors with high-frequency current superimposition over a broad range of frequencies.

Super Core? meets all high frequency wave regulations and power factor improvements, demand is on the increase for its use in not only inverter output reactors but also in active filters and in PWM converter reactors in the market sectors from consumer electronics to industrial, renewable power generation and automotives.
Super Core? meets a diverse range of customers needs since it can be formed into wound cores, such as C-cores and toroidal cores, as well as into lamination cores and glued block cores of various shapes by cutting or pressing. For example, as illustrated in the figure on the bottom right, a reactor with 4-point gaps, consisting of a combination of glued-lamination core and a flat, vertically wound coil, with excellent impedance-frequency characteristics, shows DC superimposition characteristics that are far superior to conventional wound core with one or two gaps. The low magnetostriction characteristics of JNEX CORE? reduce high frequency noise in the audible ranges of 20kHz or less, and therefore provide quiet power sources for inverters and converters.

Because of its superior low core loss characteristics, Super Core? has many advantages in high-speed motors and power generator applications -- stator, rotor, and yoke – and contributes greatly to efficiency. It is also effective in reducing noise that is caused in part by magnetostriction. Super Core? has attracted the attention for its use in electric and hybrid car motors, power generators, as well as the motors for OA devices.
