Working Principles

The MF-R075/90-AP operates based on the principle of a polymer positive temperature coefficient (PTC) material. When an overcurrent condition occurs, the PTC material heats up, causing its resistance to increase and limit the current flow. Once the fault is cleared, the PTC material cools down and returns to its low-resistance state.

Detailed Application Field Plans

The MF-R075/90-AP is suitable for various electronic devices and systems requiring overcurrent protection, including: - Battery packs - Power supplies - Automotive electronics - Industrial control systems

Detailed and Complete Alternative Models

  1. MF-RX Series: Offers a range of hold currents and voltages
  2. MF-MSMF Series: Surface mount PTC resettable fuses
  3. MF-NSMF Series: Low-resistance PTC resettable fuses for high-current applications

In conclusion, the MF-R075/90-AP is a reliable and fast-acting resettable fuse suitable for a wide range of electronic applications, providing essential overcurrent protection while offering the convenience of automatic reset. Its specifications, functional features, and alternative models make it a versatile choice for designers and engineers seeking robust circuit protection solutions.
