Working Principles

The MF-MSMF075/30-2 operates based on the principle of positive temperature coefficient (PTC) thermistors. When the current exceeds the trip current, the PTC material heats up, causing a sharp increase in resistance, which limits the current flow and protects the circuit. Once the fault condition is removed, the PTC material cools down, allowing the device to reset and resume normal operation.

Detailed Application Field Plans

The MF-MSMF075/30-2 is commonly used in various electronic applications, including: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunication equipment - Power supplies

Detailed and Complete Alternative Models

• MF-MSMF110/24-2: Higher voltage and current rating
• MF-MSMF075/60-2: Higher hold and trip current ratings
• MF-MSMF075/20-2: Lower voltage rating for specific applications

In summary, the MF-MSMF075/30-2 resettable fuse offers reliable overcurrent protection for electronic circuits, making it a valuable component in a wide range of applications.
