Common Mode Chokes
Common mode chokes are inductive components used to reduce or suppress electromagnetic interference (EMI) of the common mode in signal/power lines. They are an important component in common mode filter circuits to mitigate EMI, reduce noise, and ensure stability in electronic equipment systems. Common mode chokes are composed of two windings, bobbins, core, and other accessories. The two windings are connected in series with the signal/power line, forming a choke.
DLP11SN331HL2L
The DLP11SN331HL2L is a common-mode communication filter designed for use in distributed power supply systems that require a high level of EMI noise suppression. The filter features a wide operating temperature range, low saturation voltage, high attenuation performance, high environmental protection, and excellent ESD protection. As a specially designed and optimized component, the DLP11SN331HL2L can be widely applied in mobile phone base station power supply systems. It has good performance in improving EMI in electrical equipment and reducing ESD risks.
Application Field
The DLP11SN331HL2L is mainly used in communication systems. The filter can be applied to the transmission line that needs to reduce the common-mode interference. Moreover, the filter can effectively filter out all kinds of high-frequency interference signals on the power transmission line, and reduce the impact of high frequency electromagnetic radiation on the surrounding environment to ensure communication system\'s normal communication.
Working Principle
The DLP11SN331HL2L consists of two windings, a core and accessories. It works similar to an inductor. The current flowing through the DLP11SN331HL2L filter will generate an inductive voltage (self-inductive effect) to reduce the noise in the transmission line. This inductive effect forms an additional impedance which restricts the flow of the noise signal. At the same time, the filter can suppress the environmental electromagnetic radiation and its voltage generated in the power line, and prevent the environmental noise from affecting the normal operation of the communication system.
In addition, the DLP11SN331HL2L is equipped with an overcurrent protection element and an ESD protection element to help prevent any overvoltage, overcurrent or ESD event occurring that will damage the whole system. The filter can also control the beginning and end of the transmission line to ensure the accuracy of the power supply.
Conclusion
Common mode chokes are essential components for noise reduction in signal/power lines and for EMI and ESD protection. The DLP11SN331HL2L filter is designed for use in distributed power supply systems that require high level of EMI noise suppression and ESD protection. It has numerous applications in communication systems and has been proven to effectively minimize common mode interference, reduce environmental noise on the line, and provide overcurrent and overvoltage protection of the whole system.
