Large plate-shaped ferrite core for non-contact power supply applications.
Contactless power supply is expanding its applications from small-capacity devices like electric toothbrushes to automatic guided vehicles (AGVs) and electric vehicles (EVs) with the practical implementation of the new technology "electromagnetic resonance method." This technology requires ferrite cores, and with the expansion of applications and the need for larger capacities, there is a demand for materials that exhibit low loss and high magnetic flux density over a wide temperature range.

basic information
**Features** Currently, the adhesive method using relatively small ferrite cores is mainstream, but there is a trend towards larger sizes due to heat dissipation measures associated with increased capacity and reduction of labor. We have a wide selection of large plate-shaped block cores, allowing us to propose materials aimed at reducing high-frequency losses. Custom shapes tailored to coil specifications are also available. - Operating frequency: up to 1 MHz - Operating temperature range: -40 to 120°C - Various capacities can be accommodated by adjusting the thickness of the ferrite core. - We can also handle various custom shapes and the cutting and bonding of block cores. - Ferrite cores can be provided along with power transmission and reception coils. - While we mainly offer Mn-Zn types, Ni-Zn types are also available for use at higher frequencies.
