1. A current cable trap, comprising:
a ceramic toroid body having a first end and a second end, wherein the ceramic toroid body comprises grooves disposed on a surface of the ceramic toroid body and extending between the first end and the second end;
conductive traces formed within the grooves, wherein the current cable trap is configured to suppress common mode current in a cable; and
one or more capacitors disposed on the ceramic toroid body and configured to tune the current cable trap to a desired frequency, wherein at least one conductive trace of the conductive traces is segmented into at least two segments, and at least one capacitor of the one or more capacitors is disposed between and coupled to the at least two segments within one of the grooves.
