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 situations but operate on mechanical changes instead of charge carrier effects in semiconductors. Narrow and matched resistance tolerances used in customer premise equipment cpe central office equipment co and acess equipment.

Resettable fuse protects the circuit when over current occur by misconnection or short it is automatically returns to non operating mode and can be used repeatedly. The film is formed when a short circuit melts the fuse element causing a deposit to be seen on the inside of the fuse barrel as a film. Fuse clips fuseclips can be inserted into a printed circuit board allowing electronic and automotive fuses to protect critcal circuit components. The fuse melts open interrupting the current flow and the ptc changes from a low resistance to a high resistance to limit current flow.

The more thermally stable fuse is typically filled with sand in order to prevent the conductive film from forming. Ptc thermistor for overcurrent protection. The most obvious difference is that the ptc is resettable. When you use our website we collect personal data about you and your use of the website through cookies and analytics tools.
