Working Principles

The MF-RX014/250U-2 operates based on the principle of positive temperature coefficient (PTC). When an overcurrent condition occurs, the resistance of the PTC material increases, limiting the current flow. Once the fault is removed, the PTC material cools down and returns to a low-resistance state, allowing normal operation to resume.

Detailed Application Field Plans

The MF-RX014/250U-2 is commonly used in various electronic devices and systems, including: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment

Detailed and Complete Alternative Models

• MF-RX Series: Includes various current ratings and hold/trip current combinations
• Other Manufacturers: Bourns Multifuse, Littelfuse PTC Resettable Fuses

In conclusion, the MF-RX014/250U-2 resettable fuse offers reliable overcurrent protection with its compact design and resettable functionality. Its application spans across diverse electronic systems, making it a valuable component in modern electronic designs.
