Working Principles

The MF-RM033/240-2 operates based on the principle of positive temperature coefficient (PTC). When an overcurrent condition occurs, the PTC material heats up, causing it to transition to a high-resistance state and effectively limiting the current flow. 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 MF-RM033/240-2 is commonly used in: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment

Detailed and Complete Alternative Models

• MF-RM065/240-2
