Common Mode ChokesDLF-28-0003 application field and working principle are related to common mode chokes. Common mode chokes are components used in power solutions. They are used to filter out common mode noises and voltage disturbances on the power lines.Common mode chokes are typically used in electronic systems, such as industrial control systems, medical systems, automotive systems, and power supply systems. The main purpose of using common mode chokes is to reduce the level of radiated and conducted noise on the power lines. Common mode chokes are used to reduce common mode noise by effectively eliminating the power line\'s ability to carry such noise-waves.In a typical application, the common mode choke is placed between two power lines. This is usually done to reduce common mode current flow in the power line. The current flows through the choke, and is then split into two different paths. The first path is directly through the choke. The second path will circulate through the windings of the choke, and will loop in the opposite direction of the first path. This is why it is called a "directional" choke. The circulating current will flow in the same direction of the original current, and create an opposing magnetic field with the incoming current. This will increase the overall current\'s inductance, and reduce its peak voltage.The frequency response of a common mode choke will depend on its core material. Different cores have different characteristics, such as their magnetic permeability and overall inductance. For higher frequencies, low inductance cores, such as ferrite, are used. For lower frequencies, magnetic alloy cores, such as nickel-iron and molybdenum-iron, are used. Common mode chokes can also be designed with variable inductance, which allows for better filtering of certain frequencies.The DLF-28-0003 common mode choke is used in power supply systems to reduce the noise levels of the power lines. It is designed with a high magnetic permeability core, which makes it suitable for frequencies up to 100kHz. The choke also has a very low inductance, which helps reduce the radiated and conducted noise present on the power lines.Overall, the DLF-28-0003 is an effective and reliable common mode choke that is suitable for use in power supply systems. Its design makes it versatile and able to provide good noise suppression over a wide frequency range.
