Working Principles

The RXEF135K-2 operates based on the PPTC effect, where its resistance increases significantly when subjected to overcurrent or overtemperature conditions. This increase in resistance effectively limits the current flow through the device, protecting the circuit from damage. Once the fault condition is removed, the device self-heats and returns to a low-resistance state, ready for normal operation.

Detailed Application Field Plans

The RXEF135K-2 finds applications in various electronic circuits, including: - Overcurrent protection in power supplies - Circuit protection in battery management systems - Automotive electronics for fault tolerance - Industrial control systems for safeguarding sensitive components
