Package

The MF-RX014/250-2 is typically available in a surface-mount package, making it suitable for automated assembly processes.

Essence

The essence of the MF-RX014/250-2 lies in its ability to protect electronic circuits from overcurrent conditions without requiring replacement after each fault occurrence.

Packaging/Quantity

It is commonly packaged in reels or trays, with quantities varying based on manufacturer specifications.

Specifications

• Maximum Voltage: 30V
• Hold Current: 2.5A
• Trip Current: 5A
• Operating Temperature Range: -40°C to 85°C
• Resistance: <0.1Ω

Detailed Pin Configuration

The MF-RX014/250-2 features two pins for connection to the circuit board. The pinout configuration is as follows: - Pin 1: Input/Anode - Pin 2: Output/Cathode

Functional Features

• Overcurrent Protection: Automatically limits the current flow during overcurrent events.
• Resettable Operation: Returns to a low-resistance state once the fault condition is removed.
• Fast Response Time: Quickly reacts to overcurrent situations to prevent damage to the circuit.

Advantages and Disadvantages

Advantages

• Resettable functionality reduces maintenance and replacement costs.
• Compact size allows for integration into space-constrained designs.
• Provides reliable protection for sensitive electronic components.

Disadvantages

• Limited maximum voltage and current ratings compared to traditional fuses.
• Trip time may vary based on ambient temperature and fault conditions.

Working Principles

The MF-RX014/250-2 operates based on the PTC effect, where its resistance increases significantly when subjected to overcurrent conditions. This increase in resistance limits the current flow, protecting the circuit from damage. Once the fault is removed, the device cools down and returns to a low-resistance state, ready for normal operation.

Detailed Application Field Plans

The MF-RX014/250-2 is widely used in various applications, including: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment - Power supplies

Detailed and Complete Alternative Models

• MF-RX010/250-2
