Common-mode inductor
This amorphous magnetic‑ring common‑mode inductor is a high‑performance electromagnetic compatibility (EMC) filter specifically designed for switch-mode power supplies, variable‑frequency home appliances, and industrial equipment. Featuring a high‑permeability amorphous/nanocrystalline core paired with a symmetrically wound enameled wire coil, it effectively suppresses common‑mode interference on the power lines without compromising the device’s normal differential‑mode current transmission. With its low loss, high stability, and compact footprint, it is an ideal choice for EMI‑mitigation in modern electronic systems.

| Features | Corresponding advantage |
|---|---|
| ✅ Amorphous / Nanocrystalline magnetic core material | Compared with conventional ferrites, it offers a 3–5 times higher permeability and superior high-frequency filtering performance; it exhibits low temperature drift and low losses, maintaining stable, undiminished performance even under high-temperature, high-current conditions. |
| ✅ Symmetrical Winding Process | The magnetic fields of the two coil sets precisely cancel each other, leaving normal differential-mode currents unaffected while presenting high impedance to common-mode interference, ensuring precise filtering without unintended side effects. |
| ✅ Insulation and moisture-proof design | Outer coil insulation plus bottom sealing provides moisture, dust, and vibration protection, making it suitable for demanding industrial and home appliance environments. |
| ✅ Compact size | With equivalent filtering performance, the footprint is more than 30% smaller than that of conventional inductors, saving PCB space and aligning with the trend toward miniaturized designs. |
| ✅ High reliability | It features a wide temperature tolerance and excellent impact resistance, enabling long-term stable operation while reducing equipment failure rates and after-sales costs. |

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.
