Description

Transformer and common mode filter integration components

This creation is about a transformer and common mode filter integration component.

According to the general transformer and common mode filter, the function of multiple inductors can be designed on a single inductor. Therefore, the number of terminal electrodes on a single inductor is not only two of the two ends. However, it has more than two terminal electrodes, so it also increases the circuit design complexity of the power sensor installation on the circuit board, which is unfavorable and inconvenient for the circuit board layout layout. The difficulty in installation increases. In particular, when the inductor is mounted on the circuit board, if it is not necessary to use too many terminal electrodes, in order to short circuit the two (or more) terminal electrodes on the inductor, it is required on the circuit board. The design (layout) short-circuit electrical path increases the complexity and makes production and assembly difficult. When the common mode filter and the transformer are two-part independent components, it is not only time-consuming in the manufacturing process (such as twice the time required to manufacture the core and the winding), and the two-piece component has The problem of high material costs.
