We develop the leading-edge materials through close control of microstructures using our unique material and processing technologies. With the Mn-Zn Power Ferrite PC Series, we offer an assortment of materials to suit the intended use, such as the high frequency material, the high Bs material, the low-loss material, and the low-loss material suitable for a wide temperature range. We also mass-produce the low THD ferrite material DN70 for broadband networks, and the ferrite material DNW45 with a wide temperature range and stable characteristics suitable for high-speed LAN systems. In addition, with the DR Series of cores for coils, we have reduced the size to 0.6mm, and have developed a new low-loss material suitable for large current. For industrial use, we deal with special-purpose shapes and high-precision processing up to extra-large sizes.
