Detailed Pin Configuration

The MF-R050-2 features a radial leaded package with two leads. The detailed pin configuration is as follows: - Pin 1: Connected to one end of the PTC element - Pin 2: Connected to the other end of the PTC element

Functional Features

• Resettable: The MF-R050-2 is designed to automatically reset once the fault condition is removed, providing continuous protection.
• Overcurrent Protection: It limits the current flow in the circuit, protecting sensitive components from damage due to overcurrent conditions.

Advantages and Disadvantages

Advantages

• Resettable functionality increases the longevity of the component
• Provides reliable overcurrent protection
• Compact size for space-constrained applications

Disadvantages

• Limited maximum current handling capability compared to traditional fuses
• Sensitive to ambient temperature variations

Working Principles

The MF-R050-2 operates based on the principle of positive temperature coefficient. When the current exceeds the trip current, the PTC material heats up, causing its resistance to increase significantly, thereby limiting the current flow through the circuit. Once the fault condition is removed, the PTC material cools down, allowing the current to flow again.

Detailed Application Field Plans

The MF-R050-2 finds extensive usage in various electronic and electrical applications, including: - Overcurrent protection in battery packs - Power supply units - Automotive electronics - Industrial control systems - Consumer electronics

Detailed and Complete Alternative Models

• MF-R030-0: Lower hold current variant
• MF-R100-0: Higher hold current variant
• MF-RX050: Surface mount variant for space-constrained applications
• MF-MSMF050: SMD fuse with similar characteristics

In conclusion, the MF-R050-2 plays a crucial role in providing reliable overcurrent protection in diverse electronic and electrical systems, making it an indispensable component in modern technology.
