Abstract
An EMI filter formed with a U-shaped ferrite core with parallel first and second legs and a center leg surrounded by a grounding and shorting strap and a capacitor connected between the grounding and shorting strap and a portion of a conductor which extends between the first and second legs. Two or more of the filters can be formed as a stacked array. The filter has a substantially improved frequency response over the prior art.
