How to select a common mode inductor and what should you consider?
The selection of common mode inductors is a very important matter. The correct selection is directly related to the progress of the research and development of related products.
Common mode inductors are divided into plug-in common mode inductors and SMD common mode inductors, which are also integrated. These must be selected according to the actual circuit. If plug-in common mode inductors cannot be installed, they can only be chip common mode inductors.

From the user’s perspective when selecting a common mode inductor, it is necessary to consider the customer’s circuit board circuit design, the functional requirements for the inductor, and the corresponding package size to select a suitable common mode inductor.
Usually, when customers design circuit boards, they already have a clear understanding and requirements of what kind of common mode inductors to use. In this case, we only need to provide the corresponding common mode inductors as needed.

From the manufacturer’s technical research and development perspective: If the customer does not know the demand information for common mode inductors, or the type of common mode inductor provided does not meet the standards during testing, we need to intervene from a professional technical perspective to help customers choose and Confirm selection.
Choose the appropriate package size based on the circuit board layout. Plug-ins, SMD and integrated inductors each have their own characteristics and need to be selected based on the actual circuit design.
Impedance characteristics are an important factor to consider when selecting common mode inductors. Generally, the larger the impedance of the common mode inductor, the better, especially in the specific frequency band where filtering is required. You need to check the specifications of the common mode inductor, especially its impedance frequency curve. There are also leakage inductance size, inductance value and so on.
This situation is relatively complicated and needs to be analyzed in a targeted manner based on the problems encountered by customers in actual testing and use. For example, if it is an EMC problem, we need to analyze and select based on the rating and current.
