Disadvantages

• Limited maximum voltage compared to some traditional fuses
• May have a slightly higher initial cost compared to non-resettable fuses

Working Principles

The MF-R030-AP operates based on the principle of positive temperature coefficient (PTC) resistance. When an overcurrent condition occurs, the device heats up, causing its resistance to increase and limit 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-R030-AP is widely used in various electronic applications, including: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment - Power supplies

Detailed and Complete Alternative Models

• MF-R005-AP: 0.05A hold current
• MF-R010-AP: 0.1A hold current
• MF-R020-AP: 0.2A hold current
• MF-R050-AP: 0.5A hold current

In conclusion, the MF-R030-AP resettable fuse offers reliable overcurrent protection in a compact and resettable form factor, making it suitable for a wide range of electronic applications.
