Detailed Pin Configuration

The MF-RX065/72-0 has a standard SMD pin configuration with two terminals for surface mounting onto PCBs.

Functional Features

• Resettable: Automatically resets after the fault condition is removed
• Overcurrent Protection: Limits the current to protect the circuit components
• Compact Design: Space-saving SMD package suitable for modern electronics

Advantages and Disadvantages

Advantages

• Resettable functionality increases the lifespan of the component
• Provides reliable overcurrent protection
• Compact design saves space on the PCB

Disadvantages

• Limited maximum current handling capability compared to traditional fuses
• May have a higher initial cost compared to non-resettable fuses

Working Principles

When the current flowing through the MF-RX065/72-0 exceeds the trip current, the device heats up and changes its resistance, limiting the current flow. Once the fault is removed, the device cools down and returns to its low-resistance state, effectively resetting itself.

Detailed Application Field Plans

The MF-RX065/72-0 is commonly used in various electronic devices and systems, including: - Consumer electronics - Automotive electronics - Industrial control systems - Power supplies - Telecommunications equipment

Detailed and Complete Alternative Models

• MF-RX110/72-0: Higher hold and trip currents for increased protection
• MF-RX050/72-0: Lower hold and trip currents for more sensitive applications
• MF-RX075/72-0: Higher maximum current rating for heavy-duty applications

In conclusion, the MF-RX065/72-0 resettable fuse offers reliable overcurrent protection in a compact and resettable form factor, making it suitable for a wide range of electronic applications.
