PTC resettable fuses have been developed as an improvement upon traditional fuse-based circuits. The unique property of these new type fuses is that they will re-set themselves after a fault or short-circuit has occurred. This makes them very attractive for applications where circuit protection is a must, such as AC/DC power converters, automotive circuits, and consumer electronics devices.

The PTCMR350STE is a PTC-based resettable fuse that is designed for overcurrent protection and short-circuit protection in a wide range of applications. It features a fail-safe design and provides superior operation for currents up to 350 A. It has a wide temperature range, good current-carrying capacity, and fast response time with a resetting time of 200 ms or less.

The PTCMR350STE is a self-resetting device that prevents current overloads and short-circuits. Its operating principles are based on a thermally-sensitive ceramic enclosure containing a positive temperature coefficient (PTC) heater element. When the current through the heater element exceeds a predetermined threshold, the PTC begins to generate heat, causing its resistance to rise, and hence the current quickly decreases or is completely interrupted. After the fault situation is removed, the assembly cools to its original temperature, resetting the heater element and returning the device to its normal working state.

The PTCMR350STE is suitable for a variety of applications, including AC/DC power converters, automotive circuits, consumer electronics and battery packs. Its fast response time (<200 ms) and fail-safe design make it perfect for applications that require reliable overcurrent and short-circuit protection. The PTCMR350STE also has a wide operating temperature range (-40°C to 85°C) and is able to handle currents up to 350A, making it a good choice for many applications.

The PTCMR350STE offers reliable protection for electronic circuits and equipment. Its self-resetting function prevents costly replacement of traditional fuse-type circuit breakers and makes the device an attractive solution for continuous protection against overcurrents and short-circuits. This makes the PTCMR350STE a preferred choice for applications that require reliable current protection and circuit stability.
