The Magnetic ring coil amorphous magnetic ring common-mode inductor manufactured by Haoer Factory is a high-performance passive filter component with a core magnetic path made of amorphous alloy. It adopts a symmetrical double-winding design. It is specifically developed to suppress common-mode interference in scenarios with strong currents and wide frequency bands. Relying on the excellent magnetic properties of the amorphous magnetic core, it demonstrates far superior stability and anti-interference capability compared to traditional ferrite common-mode inductors in fields such as new energy and industrial high-power power supplies. It is a core component for electromagnetic compatibility design in high-end power systems.
Super strong anti-saturation capability, suitable for high current scenarios
The saturation flux density of amorphous magnetic cores is 2 to 3 times that of traditional manganese-zinc ferrite. Under hundreds of amperes of high current conditions, it can stably suppress common-mode interference in high-power power supply systems, and perfectly adapt to charging piles, photovoltaic inverters and other equipment.
Wide bandwidth and low loss, with wide suppression range
Magnetic Ring Coil Amorphous Magnetic Ring Common-mode Inductor's working frequency range is 50Hz to 1MHz, and the core loss is much lower than that of iron powder cores and iron-silicon-aluminum cores throughout the entire frequency band. Compared with ferrite common-mode inductors, the interference suppression effect in the low-frequency range has been significantly improved, meeting the requirements for both high and low-frequency common-mode interference control.
Wide temperature magnetic stability, strong environmental adaptability
The permeability of amorphous magnetic cores changes by less than ±5% within the wide temperature range of -55℃ to +150℃, which is much better than the temperature drift characteristics of ferrite magnetic cores. It can meet the strict temperature requirements of industrial-grade and automotive-grade equipment, and maintain stable performance in extreme high and low temperature environments.
Low magnetic leakage, excellent electromagnetic compatibility
The zero-gap design of the closed amorphous magnetic ring minimizes magnetic field radiation, resulting in minimal electromagnetic interference to surrounding sensitive components (such as MCUs, sensors), eliminating the need for additional shielding measures and simplifying the circuit layout.
High reliability, long service life
The amorphous alloy material is resistant to vibration and corrosion. The windings are closely integrated with the magnetic core without any loosening risks. It complies with the AEC-Q200 automotive standard and the IP65 protection level requirements, and can have a service life of over 100, 000 hours.
