We propose appropriate Litz wire structures tailored to your usage conditions. Starting with "stranded Litz wire," which is a wire freely twisted from multiple single wires, we also offer "concentric twisted Litz wire," where individual wires are arranged concentrically around a central conductor in one or multiple layers, and "composite twisted Litz wire," which is twisted in multiple steps based on specified shapes. Please feel free to consult us when you need assistance. [Types of twisted wire] ■ Stranded twisted wire ■ Concentric twisted wire ■ Rope twisted wire *For more details, please download the PDF or feel free to contact us.

We would like to introduce the "SQLW Square Cross-Section Litz Wire" that we handle. Compared to conventional round Litz wires, by using a square or rectangular shape, it is possible to eliminate unnecessary gaps and increase the filling ratio of stranded wires by about 20%. Additionally, the resistance value can be reduced by approximately 10-20%, and by using a square shape, the heat dissipation due to surface contact is improved, allowing for a greater current to flow. 【Lineup】 ■φ3.0 ■φ4.0 ■φ5.0 ■φ6.0 ■φ7.0 *For more details, please download the PDF or feel free to contact us.

Currently, energy storage technology is rapidly advancing, and technological innovations are still being pursued. At the same time, there is a growing expectation and demand for wireless (non-contact) power supply technology. In various fields such as electric vehicles, which are expected to grow into a significant market, as well as robotics, drones, home appliances, and medical devices, the characteristics of SQLW square cross-section litz wire can be utilized. Compared to conventional round litz wire, using square or rectangular shapes can eliminate unnecessary gaps and increase the filling ratio of stranded wire by about 20%. Additionally, the resistance can be reduced by approximately 10-20%, and since a larger cross-sectional area can be achieved, heat dissipation through surface contact is improved, allowing for a higher current flow. It is also possible to increase the number of turns while maintaining the same external dimensions as the previous round litz wire, making it suitable for the rapidly increasing demand for wireless fast charging, while also contributing to miniaturization without compromising performance.

The "Ritz wire" is an enamel wire used in high-frequency equipment. It can suppress the increase in alternating current resistance due to the skin effect and proximity effect unique to high frequencies, thereby reducing the temperature rise of the coil. Additionally, it has excellent flexibility and good winding workability. 【Features】 ■ The increase in alternating current resistance due to high frequency is small, allowing for the suppression of the coil's temperature rise. ■ The type of wire can be freely selected according to the application. ■ The number of wires and the diameter of the individual wires can be freely selected. *For more details, please download the PDF or feel free to contact us.
