A solderless, feedthrough radio frequency filter has plates with individual openings for a plurality of physically parallel, elongated conductors. To provide capacitance, the plates are constructed of electrically conductive material and the conductors covered with dielectric material where they pass through the openings. To provide inductance, the conductors are circumscribed by sets of ferrite beads adjacent to the plates. The filter may be tuned capacitively by selecting the plate thickness and tuned inductively by selecting the configuration of the beads. More complex filters may be constructed by using a plurality of plates, including nonconductive plates, and a plurality of bead sets spaced along the conductors.
