UU9.8 UU10.5 UU16 Common Mode Choke Inductor 10mH/20mH/30mH Vertical Line Filter
1.Product Description
The UU Common Mode Choke Inductor is a specialized electromagnetic component designed to suppress common - mode noise in electrical circuits. with the U - shaped core design providing a specific magnetic path structure. This inductor consists of two windings wound around the UU - shaped magnetic core in a way that common - mode currents induce a large impedance, while differential - mode currents pass through with relatively low impedance. By leveraging the magnetic properties of the core material, usually a ferrite with high magnetic permeability, it effectively attenuates common - mode noise frequencies, typically in the range from a few kilohertz to several megahertz. This makes it an essential part of power supply circuits, data communication lines, and other electronic systems where noise suppression is crucial for maintaining signal integrity and the reliable operation of electronic devices.
2.Features
(1) Unique UU type magnetic core structure
Efficient magnetic circuit: The UU type magnetic core structure provides a unique closed magnetic circuit, which can more effectively concentrate and guide the magnetic field compared to other shaped magnetic cores. This enables the inductor to efficiently transfer magnetic field energy within the magnetic core while suppressing common mode noise, reducing magnetic flux leakage to the surrounding environment and improving the inductor's ability to suppress common mode signals.
(2) High common mode impedance
Noise suppression: exhibiting high impedance characteristics for common mode currents. When a common mode noise signal passes through a circuit, high impedance will hinder its propagation, effectively suppressing common mode noise. For example, in switch mode power supply circuits, common mode noise is often generated by parasitic capacitance and inductance in the circuit. UU common mode choke inductance can significantly reduce the interference of these noises on the power output, ensuring that the power supply provides pure DC voltage to the load.
(3) Low differential mode impedance
Signal lossless transmission: presenting low impedance to differential current, allowing differential signals (i.e. normal useful signals) to pass almost unobstructed. Taking audio signal transmission as an example, audio signals are transmitted in differential mode, and the UU common mode choke inductor suppresses common mode noise without causing attenuation or distortion to the audio signal, ensuring audio quality.
Good compatibility: This feature ensures good compatibility between the common mode choke inductance and other components in the circuit, without interfering with the processing and transmission of normal signals, ensuring that the circuit can function properly.
3.Advantage
| Advantage | Explanation |
| High Common - mode Impedance | The UU common - mode choke inductor offers high impedance to common - mode currents. This effectively suppresses common - mode noise over a wide frequency range, typically from a few kHz to several MHz. In power supply circuits, it can significantly reduce the interference caused by common - mode noise, ensuring a clean DC voltage output for loads. |
| Low Differential - mode Impedance | It exhibits low impedance to differential - mode currents, allowing the normal useful signals to pass through with little attenuation or distortion. For example, in audio signal transmission, it can ensure high - quality audio while suppressing common - mode noise, and is highly compatible with other circuit components without disturbing normal signal processing. |
| Compact UU - shaped Core Structure | The UU - shaped core design provides a compact structure. It can achieve a relatively high inductance value within a limited space, making it suitable for integration into space - constrained electronic devices. This contributes to the miniaturization and lightweight design of devices such as small consumer electronics and portable medical equipment. |
| High - permeability Core Material | The inductor usually uses a core material with high magnetic permeability, like ferrite. This not only enhances the inductance performance, enabling better suppression of common - mode noise, but also features low magnetic hysteresis and eddy - current losses. As a result, it has high efficiency and long - term stability, even under continuous operation. |
