Working Principles

The MF-SM013/250-2 operates based on the principle of positive temperature coefficient (PTC) resistance. When an overcurrent condition occurs, the PTC material heats up, causing its resistance to increase significantly, effectively limiting the current flow and protecting the circuit. Once the fault is removed, the PTC material cools down, returning to its low-resistance state and allowing normal operation to resume.

Detailed Application Field Plans

The MF-SM013/250-2 is suitable for a wide range of electronic applications, including but not limited to: - Consumer electronics - Automotive electronics - Industrial control systems - Power supplies - Telecommunications equipment

Detailed and Complete Alternative Models

• MF-SM005/250-2: Lower hold and trip currents for more sensitive applications
• MF-SM020/250-2: Higher hold and trip currents for increased protection in heavy-duty circuits
• MF-SM010/250-2: Mid-range option suitable for general-purpose electronic circuits

In conclusion, the MF-SM013/250-2 surface mount resettable fuse offers reliable overcurrent protection, fast response, and a compact design, making it a versatile choice for various electronic applications.
