摘要： A fuse includes first, second, and third terminals disposed on a substrate. Respective ends of one or more primary conductors of the fuse are connected to one of the first and the second terminals. The primary conductors have a first conductivity and are configured to open when a primary current between the first and the second terminals exceeds a first predetermined threshold. One or more secondary conductors have an end connected to the third terminal. The secondary conductors are configured to ignite when a secondary current through the secondary conductors exceeds a second predetermined threshold. When ignited, the secondary conductors open the primary conductors to thereby stop the primary current.
