Ceramic Resettable Fuse

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.

Ceramic resettable fuse. Bourns ceramic ptc resettable fuses for telecom overcurrent protection. Understanding the differences in performance between the two types of devices will make the best circuit protection choice easier. 750vdc fast acting fuse ac387501 series for energy vehicle dc applications. Fuse clips fuseclips can be inserted into a printed circuit board allowing electronic and automotive fuses to protect critcal circuit components.

The more thermally stable fuse is typically filled with sand in order to prevent the conductive film from forming. 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 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. The most obvious difference is that the ptc is resettable. Resettable ptc fuses optiffuse offers a complete range of resettable fuses in radial axial and surface mount configurations. 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.
