UU9.8 / UU10.5 / UU15.7 / UU16
The EMI Filter UU Filter supplied by Haoer manufacturer achieve dual suppression of common-mode and differential-mode interference through impedance matching and magnetic field cancellation mechanism:
Common-mode interference suppression: When the common-mode interference current flows through the symmetrical double-winding, a magnetic field of the same direction is generated inside the UU-shaped magnetic core. The superposition of these magnetic fields results in a high impedance of the magnetic core, significantly attenuating the interference signal.
Common-mode interference suppression: When the common-mode interference current flows through the windings, a reverse magnetic field is generated. Part of this magnetic field cancels out in the closed magnetic circuit, and the remaining magnetic field forms a common-mode inductance, which can further suppress common-mode noise.
Normal signal conduction: There is a current flowing through the circuit for direct current or low-frequency signals. The core has an extremely low impedance, resulting in almost no signal loss, ensuring the normal operation of the equipment.
Dual filtering, efficient anti-interference: EMI Filter UU Filter simultaneously suppresses both common-mode and differential-mode interference, without the need for additional filtering components, simplifying the EMC circuit design and enhancing the filtering efficiency.
· Wide frequency band adaptation, flexible scenarios: By selecting different material cores, it can cover a wide frequency range of 50Hz - 100MHz, suitable for interference suppression requirements of various devices such as switching power supplies, frequency converters, and household appliances.
· Low magnetic leakage, good electromagnetic compatibility: The closed magnetic circuit design significantly reduces magnetic field radiation, causing minimal interference to sensitive components (such as MCUs, sensors), and no additional shielding measures are required.
· Compact size, convenient layout: The symmetrical structure of the UU-shaped magnetic core enables miniaturization of components, and the plug-in / surface-mount dual versions can adapt to different PCB layout schemes, saving installation space.
· High reliability, strong environmental tolerance: The working temperature range of EMI Filter UU Filter is wide (-40℃~+125℃), resistant to vibration and corrosion, compliant with RoHS and REACH environmental standards, suitable for industrial and consumer applications.
· Cost-effective, high: The ferrite material has a wide source and mature production process, and has significant cost advantages when applied on a large scale, outperforming ring filters with the same performance.
