• Reliable protection against overcurrent conditions

Disadvantages

• Limited maximum voltage and hold current compared to some non-resettable fuses
• May have a slightly higher initial cost compared to traditional fuses

Working Principles

The RUEF250-AP operates based on the principle of positive temperature coefficient (PTC) behavior. When the current exceeds the hold current, the device heats up, causing its resistance to increase significantly, limiting the current flow. Once the fault condition is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The RUEF250-AP is commonly used in various electronic applications, including: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment - Power supplies

Detailed and Complete Alternative Models

Several alternative models with similar characteristics and functionalities are available in the market, including: - RUEF300-AP - RUEF200-AP - RUEF350-AP - RUEF400-AP

In conclusion, the RUEF250-AP is a resettable fuse designed to provide reliable overcurrent protection in electronic circuits. Its compact design, resettable nature, and reliable operation make it suitable for a wide range of electronic applications.
