Summary of the invention
The application is intended to one of solve the problems of the technologies described above at least to a certain extent.
The application provides a kind of SMD common-mode filter with high suitability, comprising:
Paster skeleton, magnetic core and copper cash, described paster skeleton is provided with the PIN being suitable for paster, described PIN is the bendable structure comprising winding section and paster portion, described copper cash be set around described magnetic core forms winding and its lead-out wire winding on described winding section.
Further, described paster skeleton includes 4 or 8 described PIN.
Further, described lead-out wire winding on described winding section after wrap tin layers.
Further, described magnetic core is magnetic powder core or sendust core.
The beneficial effect of the application is:
By providing a kind of SMD common-mode filter with high suitability, comprise: paster skeleton, magnetic core and copper cash, paster skeleton is provided with the PIN being suitable for paster, PIN is the bendable structure comprising winding section and paster portion, copper cash be set around magnetic core forms winding and its lead-out wire winding on winding section.Like this, the lead-out wire winding of copper cash on the winding section of PIN, by paster skeleton, can realize the automatic chip mounting of whole common mode inductance coil, and in packed and transported process, PIN is flexural deformation not easily, ensure that product quality, improve production efficiency, reduce production cost.
