An implantable lead assembly includes an elongated body, a bobbin, and a conductor. The elongated body includes a distal end having an electrode and a proximal end having a header connector portion for coupling the elongated body with an implantable medical device. The bobbin is disposed in the elongated body. The conductor is disposed in the elongated body and is electrically coupled with the header connector portion and the electrode. The conductor is wound around the bobbin to form first and second inductive coils that are axially separated from each other by an inter-coil gap formed from the bobbin. The first and second inductive coils have different self resonant frequencies.
