Working Principles

The RXEF075-AP operates based on the principle of positive temperature coefficient (PTC). When an overcurrent or short circuit occurs, the PTC material heats up, causing it to transition to a high-resistance state, effectively limiting the current flow. Once the fault is removed, the PTC material cools down, returning to its low-resistance state.

Detailed Application Field Plans

The RXEF075-AP is commonly used in various electronic devices and equipment, including: - Consumer electronics - Automotive electronics - Industrial control systems - Power supplies - Battery packs

Detailed and Complete Alternative Models

Some alternative models to RXEF075-AP include: - RXEF090-AP: Higher current rating for increased protection - RXEF060-AP: Lower current rating for more sensitive applications - RXEF100-AP: Higher voltage rating for specific requirements

In conclusion, the RXEF075-AP resettable fuse offers reliable overcurrent protection with the added benefit of automatic reset, making it suitable for a wide range of electronic applications.
