Common Mode Chokes

Commonly referred to as a “Common Mode Filter” or “Common Mode Inductor,” a Common Mode Choke is a three-terminal device that is designed to reduce noise interference within electronic systems. Common Mode Chokes are one type of electromagnetic interference (EMI) reduction product, with specific applications in power supply lines and in-line noise sources. The DLM0NSN900HY2D application field and its specific working principle are described here.

DLM0NSN900HY2D Application Field

TheDLM0NSN900HY2D Common Mode Choke has specific applications in automotive, industrial, and consumer power systems. It is used to reduce noise interference in power lines and to restore signal integrity in power switching systems. The DLM0NSN900HY2D is particularly suited to the power supply applications, allowing for the flow of power with minimal distortion and limiting generated electromagnetic interference (EMI) and RF noise. It is also used in many industrial control systems, such as AC/DC converter systems, DC/DC converter systems, and automotive onboard computer systems, due to its high efficiency and excellent noise suppression performance. Additionally, its one-piece construction makes it particularly suitable for applications in consumer electronic products, saving assembly time and cost.

DLM0NSN900HY2D Working Principle

The DLM0NSN900HY2D Common Mode Choke is based on the principle of the common mode inductor. Its design consists of three terminals including two input terminals and one output terminal. When an AC (alternating current) signal is applied to the two input terminals, a voltage differential is generated between the input terminals. This voltage differential causes an induced current flow in the output terminal, which functions as a high-frequency shield to reduce the EMI level.

The DLM0NSN900HY2D also makes use of the principle of common mode inductance, which develops a reactive choke when applied to power supply lines. This choke serves to filter out high-frequency harmonics from the input signal, thus helping the system to remain stable and free from noise. In this way, the AC signal applied to the input terminals can be regulated to a more desirable level of voltage, while suppressing any unwanted noise. The three-terminal structure of the DLM0NSN900HY2D simplifies this filtering process, making it easier to reduce EMI levels within power supply systems.

Conclusion

The DLM0NSN900HY2D Common Mode Choke is a three-terminal device that is used to reduce interference in electronic systems. It is particularly suited to applications in power supply lines, as well as to industrial control systems and consumer electronic products. Its three-terminal design utilizes the principles of a common mode inductor and common mode inductance, providing a high-efficiency filtering solution to reduce EMI in power supply systems.
