They are indeed sensitive to changes, and one of those changes is the coil. The coil and the driver circuit in the ICU operate together to provide an oscillating decay of the primary magnetic field in the coil during the length of the arc. A change in the characteristics of the coil may not always have detrimental consequences for the ICU, however, it has happened. If your ICU matches the one shown in the link provided by fonzi (below), it is a TSZ 8u. If it has a smooth, stamped cover it is a TSZ 4. Both are sensitive.
