Patent ID: 6970058

Claim:
L-C type filter module comprising: at least two capacitors, at least one inductor ( 3 ) with a coil ( 3 â€²), each of the capacitors ( 2 , 2 ) comprising an elongated first element ( 4 ; 4 ) made of conductive material partially fitted, over a determined depth, in a hole or perforation ( 5 ) made in a second element ( 6 ) made of conductive material, connected electrically to the second element of the other capacitor(s) or common to the other capacitors ( 2 , 2 ), at least the internal lateral surfaces defining said hole or perforation ( 5 ) being covered with a dielectric material ( 7 ), as are the edges ( 5 ) of the openings of the hole or perforation ( 5 ) and at least parts of external surfaces of the second element ( 6 ) adjoining said edges ( 5 ), and a support body ( 8 ) carrying the coil ( 3 ) of each inductor ( 3 ), the support body ( 8 ) made of dielectric material, possibly contiguous with the second element ( 6 ) or with the dielectric coating ( 7 ) at least partially covering the external face of the second element ( 6 ).
