• Reliable overcurrent protection for enhanced circuit safety

Disadvantages

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

Working Principles

The MF-R160-2 operates based on the PPTC effect, where its resistance increases significantly when subjected to overcurrent conditions. This increase in resistance limits the current flow, protecting the circuit from damage. Once the fault is removed, the device resets to its low-resistance state, allowing normal current flow.

Detailed Application Field Plans

The MF-R160-2 is suitable for a wide range of applications, including: - Consumer electronics - Automotive electronics - Industrial control systems - Power supplies - Telecommunications equipment

Detailed and Complete Alternative Models

• MF-R005: Lower hold and trip currents for more sensitive applications
• MF-R250: Higher hold and trip currents for heavier-duty protection
• MF-R500: Increased maximum voltage rating for high-voltage applications

In conclusion, the MF-R160-2 offers reliable overcurrent protection in a compact, resettable package, making it a versatile choice for various electronic applications.
