• Trip current may not be adjustable for specific applications

Working Principles

The MF-R050 operates based on the principle of positive temperature coefficient. When an overcurrent condition occurs, the device's resistance increases, limiting the current flow and protecting the circuit. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The MF-R050 is commonly used in various electronic applications, including: - Consumer Electronics - Automotive Electronics - Telecommunications Equipment - Industrial Control Systems

Detailed and Complete Alternative Models

• MF-R030: Lower hold and trip currents for sensitive electronics
• MF-R100: Higher hold and trip currents for more robust protection
• MF-R200: Increased maximum voltage rating for high-voltage applications

In conclusion, the MF-R050 is a reliable resettable fuse with a compact design and efficient overcurrent protection capabilities. Its widespread use across different industries highlights its versatility and effectiveness in safeguarding electronic circuits.
