Abstract
A resonant circuit which forms part of a security tag for use in an electronic security system includes a fusible link which opens the circuit in response to radio frequency at the resonant frequency. The fusible link opens at a lower signal intensity than otherwise, because the substances of which it is made include at least one accelerator that promotes the fuse action.
