[Key Features & Advantages]
| Features | Core Advantages | Scenario Value |
|---|---|---|
| Amorphous alloy core material | It features high permeability and extremely low high-frequency losses, maintaining excellent impedance characteristics across a wide frequency range compared to conventional ferrite cores. | It achieves enhanced interference suppression without adding extra bulk, making it suitable for high-frequency, high-power devices. |
| Symmetrical Pure Copper Winding Design | The magnetic fields of differential-mode currents cancel each other out, while presenting high impedance only to common-mode interference, thus having no impact on the normal transmission of power supply signals. | Avoid interference with the normal operation of the circuit and ensure stable equipment performance. |
| High-purity copper wire winding | It boasts excellent electrical conductivity, low internal resistance, and minimal heat generation, enabling it to handle high currents while maintaining more stable temperature rise under long-term operation. | Reduce overall equipment wear, improve power conversion efficiency, and extend service life. |
| Integrated protective structure | The magnetic core and windings are protected by an insulating frame and an external housing, providing impact resistance and oxidation protection, with insulation performance meeting the required standards, making them suitable for demanding operating environments. | Minimize the impact of external environmental factors on components, reduce the risk of failures, and ensure compatibility with harsh operating environments such as automotive and industrial applications. |
| Compact ring structure | High space utilization and a smaller footprint compared to conventional inductors, facilitating PCB layout and integration. | Helps devices achieve miniaturization and lightweight design, meeting the demands of compact product architectures. |

Cobalt-based amorphous nanocrystalline alloy ribbon
Cobalt-based amorphous alloys, thanks to their unique microstructure, boast core advantages such as ultra-low losses and exceptionally high permeability: - Near-zero magnetostriction — ensuring noise-free operation and distortion-free signals; - Ultra-high permeability — far surpassing conventional iron-based amorphous materials and silicon steel; - Extremely low coercivity — delivering rapid response and reduced losses. - Cobalt-based amorphous alloys exhibit stable performance across a wide temperature range and at high frequencies, with strong anti-interference capabilities, making them well-suited for precision sensing and high-frequency applications. - Customized products can be tailored to meet specific customer requirements, offering features such as low noise, high sensitivity, and low-loss operation at high frequencies.
Iron-based nanocrystalline ribbon
・It combines high permeability, high saturation magnetic flux density, low coercivity, and low losses, with overall performance far superior to conventional iron-based amorphous alloys, silicon steel, and certain permalloy grades. ・It exhibits excellent frequency adaptability, featuring low losses and high efficiency at medium and high frequencies, making it suitable for a wide range of applications. ・Its cost is significantly lower than that of cobalt-based amorphous alloys, offering outstanding cost-effectiveness. ・It demonstrates excellent thermal stability and reliable, consistent performance, making it well-suited for large-scale industrial applications.
Due to the following characteristics, iron-based amorphous alloys exhibit a significant advantage in low core losses: - Thin thickness—only about one-tenth that of grain-oriented silicon steel; - High resistivity—approximately twice that of grain-oriented silicon steel; - Low coercivity—only about one-third that of grain-oriented silicon steel.
