• Inductor Coil

The market for high-power reactors is shifting from metal-based powder magnetic cores centered around dust cores to ferrite cores, enabled by advancements in power semiconductors that allow for higher frequencies.

V2X refers to the concept of utilizing the power from the onboard batteries of EVs (Electric Vehicles) and PHEVs (Plug-in Hybrid Electric Vehicles) for purposes other than vehicle operation. "V2X" is a collective term that includes V2L (Vehicle to Load), V2H (Vehicle to Home), and V2G (Vehicle to Grid). V2H (Vehicle to Home) is a system that connects vehicles and homes using a bidirectional charging system. It is expected to reduce electricity costs and ensure a power source during disasters. Large ferrite cores are used in the converter transformers employed in this system.

"Productization Risk... Preliminary Evaluation Before Mold Production" In the DTT Ferrite Group, we have traditionally responded to requests such as "We want to conduct a preliminary evaluation of one set before mold production" by cutting from sintered base materials for prototypes. However, we faced challenges such as being unable to accommodate certain shapes. Therefore, by operating a molding processing system developed internally, we have made it possible to accommodate a wide range of shapes.

• Switching Power Supply

This is a large ferrite core for reactors and transformers used in high-power power supply devices. In addition to large cores, various types of ferrite cores are also available.
