Working Principles

The MF-R020-2 operates based on the principle of positive temperature coefficient (PTC) behavior. When an overcurrent condition occurs, the device's resistance increases, limiting the current flow. Once the fault is removed, the device cools down and returns to its low-resistance state, effectively resetting itself.

Detailed Application Field Plans

The MF-R020-2 is suitable for a wide range of applications, including: - Consumer electronics - Automotive electronics - Industrial control systems - Power supplies - LED lighting

Detailed and Complete Alternative Models

For users seeking alternative resettable fuse options, the following models can be considered: 1. MF-R005-2 (Hold Current: 0.05A, Trip Current: 0.1A) 2. MF-R010-2 (Hold Current: 0.1A, Trip Current: 0.2A) 3. MF-R030-2 (Hold Current: 0.3A, Trip Current: 0.6A)

In summary, the MF-R020-2 resettable fuse offers reliable overcurrent protection with automatic reset functionality, making it a valuable component in various electronic applications.
