摘要： A TANK filter is provided for a lead wire of an active medical device (AMD). The TANK filter includes a capacitor in parallel with an inductor. The parallel capacitor and inductor are placed in series with the lead wire of the AMD, wherein values of capacitance and inductance are selected such that the TANK filter is resonant at a selected frequency. The Q of the inductor may be relatively maximized and the Q of the capacitor may be relatively minimized to reduce the overall Q of the TANK filter to attenuate current flow through the lead wire along a range of selected frequencies. In a preferred form, the TANK filter is integrated into a TIP and/or RING electrode for an active implantable medical device.

摘要： The self-resonance insertion loss dip of a feedthrough capacitor is reduced or eliminated by raising the equivalent series resistance of the capacitor, thus minimizing the capacitor Q. The equivalent series resistance of the capacitor can be raised by forming voids in the active and/or ground electrode plates of the capacitor. The electrode plates may be formed so as to have a relatively reduced thickness, or a relatively increased thickness. A conductive material having a relatively high resistivity may be used to form the active and/or ground electrode plates of the capacitor. Alternatively, the conductive material forming the electrode plates may have a dielectric material added thereto.
