• Fast response time

Disadvantages

• Limited maximum voltage and current ratings compared to some non-resettable fuses
• Sensitive to ambient temperature variations

Working Principles

The RUEF250S operates based on the principle of positive temperature coefficient (PTC) resistance. When an overcurrent or short circuit occurs, the PTC material heats up, causing it to transition to a high-resistance state and effectively limiting the current flow through the circuit. Once the fault is removed, the PTC material cools down, returning to its low-resistance state and allowing normal operation to resume.

Detailed Application Field Plans

The RUEF250S is commonly used in various electronic devices and systems, including: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment
