Resettable Fuses (PTC) | How it works, Application & Advantages
WEBOct 26, 2023 · Resettable fuses, also known as Polymeric Positive Temperature Coefficient devices (PTCs), represent a category of protective devices used in electrical circuits. PTCs provide overcurrent protection and automatic resetting functionality, making them a practical choice for safeguarding sensitive electronic components.
Resettable fuse - Wikipedia
WEBA 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.
Resettable PTC (PPTC) Fuse Basics - Codrey Electronics
WEBOct 28, 2022 · A PTC resettable fuse can open electric circuits during fault events like a traditional one-time fuse, but is automatically resettable. A PTC fuse consists of a positive temperature coefficient material whose internal resistance increases exponentially with an increase in operating temperature.
Resettable PTC Fuse Benefits, Operation and Applications
WEBOct 12, 2020 · A PTC fuse is a special fuse that will reset after power is removed from the circuit. It is a temperature-dependent resistor or thermistor whose resistance rises with increasing temperature. A PTC fuse quickly increases its resistance as a response to an overcurrent, over-temperature, or short circuit situation, to restrict the current flow.
Choosing the Correct PTC Resettable Fuse - Circuit Protection ...
WEBJun 30, 2020 · A PTC resettable fuse is a protection device only intended to operate during overcurrent and/or overtemperature events that are not normal operation and are generally undesired conditions. They are not intended to be a switch that operates numerous times in normal operation.
Fuses vs PTCs - Littelfuse
WEBThe traditional fuse and the Polymer based PTC (positive temperature coefficient) device represent the most common solutions employed. Understanding the differences between these two components simplifies choosing the best protection device for the application.
