A feed-through filter assembly such as may be used in an implantable medical device. The assembly includes a conductive mounting element which may be hermetically sealed to an outer housing of the implantable medical device. In many embodiments, the conductive mounting element will be a conductive canister in which a feed-through filter structure is located. Alternatively, the conductive mounting element may include a suitable subplate structure. Because the filter structure exhibits both varistor and capacitive characteristics, effective transient suppression and interference filtering is achieved in a single package. Secondary filtering may be provided downstream of the filter assembly for additional interference filtering at lower frequencies. |
