Molded common mode ferrite filter for electronic sensors

摘要

A method for forming a common mode filter for an electronic sensor and a common mode filter apparatus thereof is disclosed. A common mode filter may be molded across electrical conductors associated with the electronic sensor to thereby provide an enhanced EMC performance for the electronic sensor. The common mode filter is thus integrated with the electronic sensor rather than implemented as a separate common mode filter component. The common mode filter may comprise a ferrite filter molded across the electrical conductors associated with the electronic sensor. The electrical conductors may comprise electrical components such as, for example, a leadframe or leadwires associated with the electronic sensor. Additionally, the common mode filter can be configured as a pre-molded tie bar. Such a pre-molded tie bar may be configured as a ferrite tie bar.
