Working Principles

The MF-R020-AP operates based on the principle of positive temperature coefficient (PTC) resistance. When an overcurrent condition occurs, the device heats up, causing the resistance to increase and effectively limiting the current flow. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The MF-R020-AP is widely used in various electronic applications, including: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment

Detailed and Complete Alternative Models

• MF-R005-AP: 0.05A hold current
• MF-R010-AP: 0.1A hold current
• MF-R030-AP: 0.3A hold current
• MF-R050-AP: 0.5A hold current

In conclusion, the MF-R020-AP resettable fuse offers reliable overcurrent protection in a compact form factor, making it an ideal choice for modern electronic designs.
