Common-mode Inductor - Full Spec PCB Mount EMI Filter Inductive Device

Haoer Electronics' Common-mode inductor is a core component for suppressing common-mode electromagnetic interference. Its design of two wires wound together on a high magnetic permeability magnetic ring presents a high impedance to common-mode noise (interference between the line and ground), while having an extremely low impedance to differential-mode signals (useful working current). It can effectively prevent external interference from invading the equipment, and at the same time prevent the equipment's noise from polluting the power grid, thereby enhancing the safety and reliability of the system. Our Common-mode inductor series includes products such as Iron Oxide Common-mode Inductor, Magnetic Ring Coil Amorphous Magnetic Ring Common-mode Inductor, and others.

Core features

· Common-mode noise destroyer: Effectively suppresses electromagnetic interference between the lines and the ground, reduces radiation and conducted emissions.

· Symmetrical balanced design: Ensures that the two windings are highly symmetrical, avoids mode conversion, and enhances filtering effect.

· Safe and reliable: Uses enameled wires and insulating materials that comply with safety regulations to ensure long-term stable operation.

Choose Haoer: Our common-mode inductors cover a wide range of requirements from consumer electronics to industrial drives, and are the essential choice for your products to achieve excellent EMC performance and comply with international standards.
