    摘要： A thermally protected metal oxide varistor includes a body, a first electrode, a thermal fuse, and a glue. The body is made up of a crystalline microstructure including zinc oxide mixed with one or more other metal oxides. The first electrode is located on one side of the body and is connected to a first lead wire. The thermal fuse is connected between the first electrode and the first lead wire. The glue is to be deposited over the thermal fuse as well as over a top portion of the first lead wire.

    摘要： An embodiment of an electrically trimmable electronic device, wherein a resistor of electrically modifiable material is formed by a first generally strip-shaped portion and by a second generally strip-shaped portion, which extend transversely with respect to one another and are in direct electrical contact in a crossing area. The first and second portions have respective ends connected to own contact regions, coupled to a current pulse source and are made of the same material or of the same composition of materials starting from a same resistive layer of the material having electrically modifiable resistivity, for example, a phase-change material, such as a Ge—Sb—Te alloy, or polycrystalline silicon, or a metal material used for thin-film resistors. The trimming is performed by supplying a trimming current to the second portion so as to heat the crossing area and modify the resistivity thereof, without flowing longitudinally in the first portion.

    摘要： An embodiment of a resistor formed by at least one first portion and one second portion, electrically connected to one another and with different crystalline phases. The first portion has a positive temperature coefficient, and the second portion has a negative temperature coefficient. The first portion has a first resistivity, and the second portion has a second resistivity, and the portions are connected so that the resistor has an overall temperature coefficient that is approximately zero.
