Working Principles

The RXEF010S operates based on the principle of positive temperature coefficient (PTC) resistance. When an overcurrent condition occurs, the resistance of the device increases, limiting the current flow and protecting the circuit. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The RXEF010S is commonly used in various electronic devices and equipment, including: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment

Detailed and Complete Alternative Models

  • RXEF020S: Higher trip current rating
  • RXEF005S: Lower hold current rating
  • RXEF015S: Intermediate hold and trip current ratings

In conclusion, the RXEF010S resettable fuse provides reliable overcurrent protection in electronic circuits with its fast-acting and resettable features. While it has limitations in terms of maximum voltage and power handling, it is widely used in diverse applications across different industries.
