A transducer component (1) comprises a first core part (10) with a middle limb (11) and a second core part (20) with a middle limb (21), wherein a front face (110) of the middle limb (11) of the first core part (10) and a front face (210) of the middle limb (21) of the second core part (20) face each other. The first and second core parts (10, 20) each have a contact area (130, 230) with a respective gradient. A width of a gap (30) between the front face (110) of the middle limb (11) of the first core part (10) and the front face (210) of the middle limb (21) of the second core part (20) is dependent on a position at which the contact surface (130) of the first core part (10) contacts the contact surface (230) of the second core part (20).
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.
