PTC resettable fuses (PTCs) are designed to protect low-voltage, high-current electronic circuits and devices from damage caused by excessive current. The main distinguishing feature of this type of fuse is its ability to reset itself after current overload occurs, thus preventing costly repairs and replacements. The MF-SD013/250-2 is one of the most popular PTCs currently on the market, and has helped to revolutionize the way circuit protection devices are used.

The MF-SD013/250-2 is carefully designed to provide the highest level of protection against overcurrent damages and is suitable for use in a variety of applications. This PTC features an innovative design-in safety feature that limits the maximum power dissipation under overload conditions, making it especially suitable for sensitive thermal management applications. The MF-SD013/250-2 also features enhanced tolerance to line voltage variations and low contact resistance during normal operation.

The MF-SD013/250-2 works on the principle of self-resetting after an overcurrent occurs. This PTC uses an electromechanical mechanism to trip the fuse and deactivate the circuit when an overload voltage is sensed. Once the overcurrent is eliminated, the PTC will reset automatically and reactivate the circuit. This is an important safety feature for circuit protection, as it helps to prevent damage to the circuit and prevents costly repairs.

The PTC resettable fuse is suitable for a variety of applications, including DC circuit protection, waste heat monitoring systems, power supplies, industrial automation equipment, battery charging, and more. The fuse can also be used as part of a circuit protection system, providing extra protection against overcurrent or power surges. Additionally, the fuse is widely used in applications where changeable parameters need to be taken into account, such as in variable-voltage, watt-hour meter circuits.

The MF-SD013/250-2 is just one example of how PTC resettable fuses can provide protection against overcurrent protection in a variety of applications. Other types of PTCs are available, offering a wide range of protection ratings and trip current levels to suit different needs. By understanding the operating principles and features of these fuses, designers and engineers can make informed decisions when selecting the right PTC for their applications.
