  • Ferrite core
    Patent number: 7078995
    Abstract: A core for minimizing the footprint of a core-based components while also minimizing the total harmonic distortion exhibited by the component. The core (40) includes a back wall portion (42), a central wall portion (44), and an outside wall portion (46). The back wall portion has a front (48) and a back (49), with a lower end (51), an upper end (52), and a pair of sides (54,55) extending between the lower and upper ends. The central leg portion protrudes from the front of the back wall portion, and the central leg portion is substantially centrally located on the front of the back wall portion. The outside wall portion protrudes from the front of the back wall portion. The central leg portion is elongated along a first axis extending between the upper and lower ends of the back wall portion. Optionally, the central leg portion is spaced from the lower edge of the back wall portion.

  • Ferrite core
    Patent number: 6501362
    Abstract: A core for minimizing the circuit board footprint of a core-based component while also minimizing the total harmonic distortion exhibited by the component. The core includes a back wall portion, a central wall portion, and an outside wall portion. The back wall portion has a front and a back, with a lower end, an upper end, and a pair of sides extending between the lower and upper ends. The central leg portion protrudes from the front of the back wall portion, and the central leg portion is substantially centrally located on the front of the back wall portion. The outside wall portion protrudes from the front of the back wall portion. In one aspect of the invention, the central leg portion is elongated along a first axis extending between the upper and lower ends of the back wall portion. In another aspect of the invention, the central leg portion is spaced from the lower edge of the back wall portion.
