Abstract

The disclosure relates to EMI filters and the like wherein the possibility of dendrite formation between electrodes is substantially eliminated. This is accomplished by encasing any material forming a part of the filter or the like which is capable of supporting dendrite growth within a material that does not support the growth of dendrites so that any ionized moisture medium cannot come into intimate contact with the material capable of supporting dendrite growth and so that there is no direct path from one dendrite growth supporting electrode across the medium to the other dendrite growth supporting electrode. The encasing material is preferably gold, aluminum or platinum.
