Abstract
A protective device for excess current utilizes a fuse that incorporates a printed circuit board. The printed circuit board has a trace on one side which is of a desired width, length, and thickness of material for opening if excess current for a selected duration of time is reached. The printed circuit board is mounted in an insulated housing. The lower side of the substrate may also have a conductive layer connected to the housing or ground. The printed circuit board and overvoltage protector may be tailored for impedance matching. An excess voltage protector may be incorporated with the printed circuit board for conducting to ground if excessive voltage is encountered. The housing has two terminals which are connected to the printed circuit board and voltage protector. These terminals may be conventional coaxial cable connectors.
