[Basic Knowledge of Coils] A must-see for those struggling with space-saving and cost reduction!

[Basic Knowledge of Coils] A must-see for those struggling with space-saving and cost reduction!

Establishment of the winding device program! We can undertake the development of prototype coils with higher performance!

For a long time, wires have supported the evolution of electricity and electronic components with their round shape. However, around the year 2000, square wires were commercialized as a type of wire that could further enhance the performance of the coil section. "Square Wire Coils" can exhibit the required characteristics for coils by utilizing square wires, which offer benefits such as increased occupancy rate, advantages of the skin effect, improved heat dissipation, space-saving, and increased power. Applications range from electronics and electrical products to automotive industry equipment, aerospace industry equipment, and space industry equipment. 【Features】 ■ Improved occupancy rate ■ Advantages of the skin effect ■ Increased power of the coil ■ Enhanced heat dissipation ■ Space-saving *For more details, please refer to the PDF materials or feel free to contact us.

Coil Amorphous Slit Gap Coil

Coil Amorphous Slit Gap Coil

Implemented slit gaps in iron-based amorphous wound cores to achieve high capacity and low noise.

Amorphous slit gap coils, by adopting a slit gap core, allow for a diverse selection of gap widths and the number of gaps, enabling the supply of coils with excellent DC superimposition characteristics without core saturation even at high currents. Since no gap material is used and a potting method is employed, the occurrence of sound due to core peeling has been significantly reduced. Additionally, issues such as forgetting to insert gap material or it falling out have been eliminated. The core is designed with a leftover section, providing swinging characteristics. It has become possible to supply the optimal core tailored to the DC superimposition characteristics required by the coil. 【Features】 ○ Slit gap cores allow for a variety of gap processing ○ Potting method adopted ○ Significant reduction in sound due to core peeling ○ No forgetting to insert gap material or falling out ○ Possesses swinging characteristics For more details, please contact us or download the catalog.
