A surge protector includes a housing having therein a wire wound resistor and a fuse separated by a partition wall. In one embodiment for use with high density information transmission, the resistor is of very low value and preferably is 5.6 ohms. The leads from the resistor and fuse are glued in position. The resistor wire is wound about a mandrel and is widely spaced to prevent arcing between adjacent coils of the resistor. A high temperature coating covers the resistor coils and mandrel effectively immobilizing the coils from movement in response to a magnetic field generated when high voltage is applied to the resistor. A cover closes the housing and conceals the components. The housing is empty of potting material.
