Common mode chokes (CMC) are used for sharply reducing common mode interference while allowing differential mode signals to pass through with minimal attention. CMCs come in various shapes and sizes, from very simple and economical filters to sophisticated ones optimized for certain purposes. The CMT4-6-R is a type of CMC that is characterized by its four cores, six layers, and rich feature set.

The CMT4-6-R basic application field is DC/DC converters, AC/DC adapters, and Power over Ethernet (PoE). It offers a wide variety of features, such as immunity to radiated and conducted interference, immunity to short-term overloads, high insertional loss, low insertion inductance, and low distributed capacitance. This makes the CMT4-6-R an excellent choice for the protection of sensitive electronic components from EMI.

The working principle of the CMT4-6-R involves four distinct stages. First, the EMI\'s high-frequency signals are received by a pair of windings. Second, the windings are connected in series to form a loop. Third, the loop is connected to a conductive core, which provides a low-inductance path for the common-mode current to be diverted away. Fourth, the resulting current is diverted to an additional pair of windings, thus completing the circuit.

The CMT4-6-R has a number of advantages over other common mode chokes, including its design features, which help to ensure efficient operation and excellent filtering performance. In addition, due to its multiple cores, the CMT4-6-R provides a higher level of immunity to conducted and radiated interference, allowing it to be used in more demanding applications.

Common mode chokes are invaluable tools for protecting sensitive electronics from EMI interference. The CMT4-6-R is a particularly reliable and efficient model, offering a high level of protection and featuring a number of useful design advantages. With its four cores, six layers, and other features, the CMT4-6-R is an excellent choice for DC/DC converters, AC/DC adapters, and Power over Ethernet applications.
