Advantages and Disadvantages

Advantages: - Resettable design for repeated use - Fast response time - Compact size

Disadvantages: - Limited maximum voltage rating - May experience nuisance tripping under certain conditions

Working Principles

The RXEF010-2 operates based on the principle of positive temperature coefficient (PTC) resistance. When an overcurrent event occurs, the PTC material heats up, causing its resistance to increase and limit the current flow. Once the fault is removed, the PTC material cools down, allowing the device to reset.

Detailed Application Field Plans

The RXEF010-2 is commonly used in various electronic circuits such as power supplies, battery packs, and control boards to protect against overcurrent conditions. It is suitable for applications where automatic recovery from overcurrent events is desired.
