A band-reject filter is provided for a lead of an active medical device. The band-reject filter comprises a capacitor connected in shunt with an inductor. The capacitor and the inductor that are interconnected in shunt are placed in serial with the lead of AMD, wherein values of capacitance and induction are selected to enable the band-reject filter to resonate at a selected frequency. Q value ofthe inductor ca be relatively maximized and Q value of the capacitor can be relatively miniaturized, so as to reduce the total Q value of the band-reject filter and then to attenuate currents flowingby the lead along the range of the selected frequency. In a preferably form, the band-reject filter is integrated into TIP and/or RING electrodes for active implantable medical devices.
