Filter inductor for heavy-current application
First Claim
1. A passive magnetic component, comprising:
- a magnetic core; and
a winding,wherein the winding includes (1) a C-shaped section having a first end and a second end, (2) first and second arm sections, the first arm section extending laterally from the first end of the C-shaped section and the second arm section extending laterally from the second end of the C-shaped section, and (3) first and second inductor pins, the first inductor pin extending substantially perpendicular from an end of the first arm section and the second inductor pin extending substantially perpendicular from an end of the second arm section.

Abstract
A filter inductor for high-current applications. The filter inductor includes a magnetic core and a winding. The winding includes a shaped section having opposing ends, a pair of arm sections laterally extending from the opposing ends of the shaped section, respectively, and a pair of inductor pins, each extending perpendicular from an end of a respective arm section. The magnetic core includes a first core portion and a second core portion. The first core portion includes a recessed channel configured to receive the shaped section of the winding. The second core portion includes a pair of recessed regions configured to receive the pair of arm sections of the winding, respectively. The first core portion and the second core portion are coupled in contact to one another to secure the shaped section of the winding within the magnetic core. The filter inductor can be edge-mounted to a printed circuit board.
