Working Principles

The MF-R075/90-0 operates based on the PTC effect, where its resistance increases significantly when subjected to an overcurrent condition. This increase in resistance limits the current flow, providing protection to the circuit. Once the fault is removed, the device self-resets as it cools down, restoring normal operation.

Detailed Application Field Plans

The MF-R075/90-0 is suitable for a wide range of applications, including: - Consumer electronics - Power supplies - Battery packs - Automotive electronics - Industrial control systems

Detailed and Complete Alternative Models

• MF-R050/90-0 (Hold Current: 0.5A, Trip Current: 1A)
• MF-R110/90-0 (Hold Current: 1.1A, Trip Current: 2.2A)
• MF-R150/90-0 (Hold Current: 1.5A, Trip Current: 3A)

In conclusion, the MF-R075/90-0 resettable fuse offers reliable overcurrent protection with the added advantage of self-recovery, making it a valuable component in various electronic applications.
