Working Principles

The MF-RX012/250-2-0 operates based on the principle of positive temperature coefficient (PTC). When the current exceeds the hold current, the device heats up and its resistance increases, limiting the current flow. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The MF-RX012/250-2-0 is commonly used in various electronic circuits requiring overcurrent protection, such as: - Power supplies - Battery management systems - Automotive electronics - Consumer electronics

Detailed and Complete Alternative Models

• MF-RX005/250-2-0: 2.5A, 5V
• MF-RX020/250-2-0: 2.5A, 20V
• MF-RX035/250-2-0: 2.5A, 35V
• MF-RX050/250-2-0: 2.5A, 50V

In conclusion, the MF-RX012/250-2-0 resettable fuse offers reliable overcurrent protection with its compact design and high current rating, making it suitable for a wide range of electronic applications.
