WebJan 3, 2006 · FIG. 1 shows a schematic diagram of a conventional poly fuse trimming circuit. A poly fuse 101 is coupled between two pads 100 and 100′.When there is a voltage difference between the pads 100 and 100′, current flows through the poly fuse 101.If the voltage difference is large enough, a large current breaks the poly fuse 101.In such a … A resettable fuse or polymeric positive temperature coefficient device (PPTC) is a passive electronic component used to protect against overcurrent faults in electronic circuits. The device is also known as a multifuse or polyfuse or polyswitch. They are similar in function to PTC thermistors in certain … See more A polymeric PTC device is made up of a non-conductive crystalline organic polymer matrix that is loaded with carbon black particles to make it conductive. While cold, the polymer is in a crystalline state, with the carbon forced … See more These devices are often used in computer power supplies, largely due to the PC 97 standard (which recommends a sealed PC that the user never has to open), and in aerospace/nuclear applications where replacement is difficult.
