Disadvantages

• Limited maximum voltage and current ratings compared to traditional fuses
• Trip time may be longer than some application requirements

Working Principles

The MF-S175 operates based on the principle of positive temperature coefficient (PTC) thermistors. When an overcurrent condition occurs, the PTC material heats up, causing a sharp increase in resistance, which limits the current flow and protects the circuit. Once the fault is removed, the PTC material cools down, allowing the fuse to reset.

Detailed Application Field Plans

The MF-S175 is commonly used in the following applications: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment - Power supplies

Detailed and Complete Alternative Models

• MF-R075: Lower current rating alternative
