An anti-surge winding fusible resistor fuse includes: a first column, in combination with a first cap, a first fuse wire wound around the first column at intervals and in combination with the first cap; a second fuse wire, coated on a second column in combination with the first column; a first ring, configured on a contact of the first column with the second fuse wire, and the first fuse wire in combination with the first ring; an insulation body, in combination with the second fuse wire; a third column, in combination with the insulation body and a second cap, a third fuse wire wound around the third column at intervals and in combination with the second cap; and a second ring, covered on the second fuse wire, insulation body and third column, and the third fuse wire in combination with the second ring.

A polymer positive temperature coefficient (PPTC) material is provided. The PPTC material may include a polymer matrix that defines a PPTC body, and further includes a high temperature polymer. The PPTC material may include a conductive filler component, disposed in the polymer matrix, an arc suppressant, and a high temperature antioxidant, disposed in the polymer matrix.

A circuit protection device including a positive temperature coefficient (PTC) device and a backup fuse electrically connected in series with one another, the backup fuse comprising a quantity of solder disposed on a dielectric chip and having a melting temperature that is higher than a trip temperature of the PTC device, wherein the a surface of the dielectric chip exhibits a de-wetting characteristic relative to the solder such that, when the solder is melted, the solder draws away from the surface to create a galvanic opening in the backup fuse.

A fuse device including a fuse component, a first electrode, disposed on a first side of the fuse component, a second electrode, disposed on a second side of the fuse component, and a phase change component, disposed in thermal contact with the fuse component. The fuse component may comprise a fuse temperature, wherein the phase change component exhibits a phase change temperature, the phase change temperature marking a phase transition of the phase change component, and wherein the phase change temperature is less than the fuse temperature.
