Working Principles

The RUEF900K-2 operates based on the principle of positive temperature coefficient (PTC) behavior. When an overcurrent condition occurs, the device heats up, causing its resistance to increase and limit the current flow. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The RUEF900K-2 is commonly used in various electronic devices and systems, including: - Consumer electronics - Automotive electronics - Industrial control systems - Power supplies - Battery management systems

Detailed and Complete Alternative Models

Several alternative models to the RUEF900K-2 include: - RUEF1100K-2 - RUEF700K-2 - RUEF1200K-2 - RUEF500K-2

These alternatives offer varying hold currents, trip currents, and voltage ratings to suit different application requirements.

In conclusion, the RUEF900K-2 resettable fuse provides reliable overcurrent protection in a compact and resettable form factor. Its specifications, functional features, advantages, and application field plans make it a valuable component in modern electronic designs.
