Micro fuses radial leaded pcb mounted fuse for use in electronic applications. Fuse clips fuseclips can be inserted into a printed circuit board allowing electronic and automotive fuses to protect critcal circuit components. Narrow and matched resistance tolerances used in customer premise equipment cpe central office equipment co and acess equipment. Cooper bussmann 3 pack 30 amp time delay plug fuse.

750vdc fast acting fuse ac387501 series for energy vehicle dc applications. We may also collect personal data such as your name job title company name address email address and telephone number either directly from you or by combining information we collect through other sources. Ptc thermistor for overcurrent protection. Understanding the differences in performance between the two types of devices will make the best circuit protection choice easier.

The fuse melts open interrupting the current flow and the ptc changes from a low resistance to a high resistance to limit current flow. 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. 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.

Bolt mounting 1000vdc fast acting fuse for dc applications a181001a series. The more thermally stable fuse is typically filled with sand in order to prevent the conductive film from forming.
