Common mode chokes (CMCs) are a type of electromagnetic device designed to cancel out common mode signals. They are often used in applications such as high-voltage power lines and cable TV. CMCs typically include two separate windings wound around an inductor core in order to render it insensitive to common mode signals.

ELF-17N002A is one such common mode choke. This component is designed for power-line applications, where it is used to filter out common-mode interference. It is made up of two windings that are wound in reverse directions on a ferrite-based core, creating an inductance that can reduce the level of common-mode inductive noise. This product is designed with a shield that provides additional protection against EMI.

The working principle of ELF-17N002A is based on the fact that common mode currents will induce a voltage in the windings, due to complex magnetic fields generated by the combination of the winding currents. This voltage has the ability to cancel out common mode signals, which are thentransmitted to ground instead. This is achieved by the two windings having an equal but opposite direction of current, thus creating an opposite field. This creates an effective inductance which impedes the flow of common-mode currents.

In terms of application, ELF-17N002A is often used in power-line applications, such as power lines and TV cables, in order to filter out any common-mode noise which could otherwise interfere with operation. This product has also been used in other applications such as data-transmission lines, in order to reduce interference from external sources.

ELF-17N002A is a popular choice for power-line applications due to its high efficiency and low cost. It is capable of handling up to 2A of current, making it suitable for high-power applications. In addition, it provides excellent noise cancellation and also offers protection against EMI.

Overall, ELF-17N002A is a compact and effective solution for common-mode noise cancellation. It is designed with two reverse-wound windings that create an inductance which reduces the level of common-mode inductive noise. In terms of applications, it is mainly used in power-line applications, such as power lines and cable TV, offering an effective solution for interference reduction.
