• Resistance: <1Ω

Detailed Pin Configuration

The MF-R030-0-A0 typically has two pins for surface mounting onto a PCB. The specific pin configuration is as follows: - Pin 1: Connected to the input circuit - Pin 2: Connected to the output circuit

Functional Features

• Resettable: Unlike traditional fuses, the MF-R030-0-A0 can return to its normal state after the overcurrent condition is removed.
• Overcurrent Protection: When the current exceeds the rated value, the fuse interrupts the circuit to protect the components downstream.
• Compact Design: Its small size makes it suitable for applications with space constraints.

Advantages and Disadvantages

Advantages

• Resettable nature increases longevity and reduces maintenance costs.
• Compact size allows for integration into small electronic devices.

• In some cases, the reset time may cause a temporary interruption in the circuit operation.

Working Principles

The MF-R030-0-A0 operates based on the principle of positive temperature coefficient (PTC). When the current exceeds the rated value, the device heats up, causing its resistance to increase significantly, thereby limiting the current flow.

Detailed Application Field Plans

The MF-R030-0-A0 is commonly used in various electronic devices and systems, including: - Consumer electronics - Automotive electronics - Industrial control systems - Medical devices - Telecommunications equipment

Detailed and Complete Alternative Models

• MF-R005-0-A0: Rated Current 5mA, Hold Current 10mA, Max Voltage 30V
• MF-R110-0-A0: Rated Current 1.1A, Hold Current 2.2A, Max Voltage 30V
• MF-R500-0-A0: Rated Current 5A, Hold Current 10A, Max Voltage 30V

In summary, the MF-R030-0-A0 resettable fuse offers compact, reliable overcurrent protection for various electronic applications, with the added benefit of being resettable. Understanding its specifications, pin configuration, functional features, and alternative models is crucial for effective integration into electronic designs.
