Resettable fuse - Wikipedia
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.
A Comprehensive Guide to Resettable Fuses - element14 …
May 10, 2023 · A resettable fuse is a device that protects electronic circuits from damage caused by overcurrent conditions, overloads, overheating, or short circuits. There are two types of resettable fuses: traditional radial lead and SMD chip packages.
Resettable PTC Fuse Benefits, Operation and Applications
Oct 12, 2020 · Positive temperature coefficient (PTC) fuses, also known as resettable fuses, enable such protection. In this article, we will discuss PTC fuses, how they work, their benefits, and applications. Overview.
Resettable PTC (PPTC) Fuse Basics - Codrey Electronics
Oct 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.
The Difference Between Traditional and Resettable Fuses
To avoid the need to replace fuses or entire circuits, resettable PTC fuses may be used. PTC fuses reset themselves and can continue to protect circuits without the need for replacement, reducing down-time and extending the life of the application.
PolySwitch Resettable PTCs Devices - Littelfuse
Littelfuse PolySwitch and POLY-FUSE devices are Polymeric Positive Temperature Coefficient (PPTC) devices which offer a resettable overcurrent protection alternative, thereby reducing warranty, service and repair costs.
Choosing the Correct PTC Resettable Fuse - Circuit Protection ...
Jun 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.
A Comprehensive Guide to Resettable Fuses | RS - RS Components
Apr 29, 2024 · Resettable fuses, also known as polymeric positive temperature coefficient (PPTC) devices or polyfuse, operate on a fascinating principle that involves their material properties responding to changes in electrical current.
Positive Temperature Coefficient (PTC) resettable fuses are simple, cost-effective overcurrent protection devices. These thermistor-based components protect circuits and downstream components against too much current due to an overload or short circuit fault condition.
