Classification of EMC Countermeasure Components and Their Roles
EMC countermeasure components are electronic components used for EMC countermeasures against noise. Specifically, they are components, such as capacitors and filters, as shown in Figure 1, and the phrase “EMC countermeasure components” is generally used to describe them. Therefore, there are no specific objects called EMC countermeasure components. In addition, among the EMC countermeasure components, there are general-purpose components that are used for other purposes than EMC countermeasures, such as capacitors and coils. However, many of the components are used only for EMC countermeasures.
