  • Current Rating: 3A
  • Hold Current: 3A
  • Trip Current: 6A
  • Operating Temperature Range: -40°C to 85°C
  • Maximum Time-to-Trip: 60 seconds at 200% of rated current

Detailed Pin Configuration

The MF-RX300/72-AP has two terminals for surface mount installation. The pin configuration is as follows: - Pin 1: Input terminal - Pin 2: Output terminal

Functional Features

  • Resettable: Automatically resets after the fault condition is removed
  • Overcurrent Protection: Trips and opens the circuit when the current exceeds the rated value
  • Compact Design: Space-saving surface mount package

Advantages and Disadvantages

Advantages

  • Resettable functionality increases product lifespan
  • Compact design saves space on the PCB

Working Principles

The MF-RX300/72-AP operates based on the principle of positive temperature coefficient (PTC). When the current through the device exceeds the trip current, the PTC material heats up, causing a sharp increase in resistance, which effectively opens the circuit and interrupts the current flow. Once the fault condition is removed, the PTC material cools down, allowing the device to reset.

Detailed Application Field Plans

The MF-RX300/72-AP is commonly used in various electronic devices and systems, including: - Power supplies - Battery packs - LED lighting - Consumer electronics - Automotive electronics

Detailed and Complete Alternative Models

  • MF-RX110/72-AP: Lower current rating variant
  • MF-RX600/72-AP: Higher current rating variant
  • MF-RX300/48-AP: Lower voltage rating variant
  • MF-RX300/90-AP: Higher voltage rating variant

In conclusion, the MF-RX300/72-AP resettable fuse offers compact overcurrent protection with a high current rating, making it suitable for a wide range of electronic applications.
