• Maximum Time-to-Trip: 60 seconds at 200% of rated current

Detailed Pin Configuration

The MF-RX160/72-AP has two terminals for connection within the circuit. The pin configuration is as follows: - Pin 1: Input terminal - Pin 2: Output terminal

Functional Features

• Resettable: Unlike traditional fuses, the MF-RX160/72-AP can return to its normal operating state after the fault condition is removed.
• Overcurrent Protection: It effectively protects the circuit from overcurrent conditions, preventing damage to sensitive components.

Advantages and Disadvantages

Advantages

• Resettable functionality increases the lifespan of the component
• Compact design saves space on the circuit board
• High current rating allows for versatile applications

Disadvantages

• Limited maximum voltage rating may not be suitable for high-voltage applications
• Trip time may be longer compared to non-resettable fuses

Working Principles

When the current flowing through the MF-RX160/72-AP exceeds the trip current, the device heats up and undergoes a structural transformation, causing it to switch from a low-resistance to a high-resistance state. This interrupts the current flow, providing overcurrent protection to the circuit. Once the fault is removed, the device cools down and returns to its original low-resistance state.

Detailed Application Field Plans

The MF-RX160/72-AP is commonly used in various electronic devices and systems, including: - Power supplies - Battery packs - LED lighting - Consumer electronics

Detailed and Complete Alternative Models

• MF-RX110/72-AP: Lower hold current rating (1.1A) for more sensitive applications
• MF-RX250/72-AP: Higher hold current rating (2.5A) for applications requiring greater current tolerance
• MF-RX160/48-AP: Lower voltage rating (48V) for applications with lower voltage requirements

In conclusion, the MF-RX160/72-AP is a resettable fuse designed to provide reliable overcurrent protection in electronic circuits. Its compact design, high current rating, and resettable functionality make it a versatile choice for various applications.
