Working Principles

RUEF110S operates based on the principle of positive temperature coefficient (PTC). When an overcurrent condition occurs, the resistance of the device increases, limiting the current flow. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

  • Consumer electronics
  • Automotive electronics
  • Industrial control systems
  • Telecommunications equipment
