• High resistance during overcurrent conditions

Package

The MF-RX135/72-2 is typically packaged in tape and reel for automated assembly processes.

Essence

The essence of the MF-RX135/72-2 lies in its ability to provide reliable overcurrent protection without the need for replacement after a fault condition.

Packaging/Quantity

It is commonly available in reels containing a specific quantity, such as 1000 pieces per reel.

Specifications

• Hold Current: 1.35A
• Trip Current: 2.7A
• Voltage Rating: 72V
• Operating Temperature Range: -40°C to 85°C
• Maximum Time-to-Trip: 20 seconds at 200% of rated current

Detailed Pin Configuration

The MF-RX135/72-2 typically has two pins for connection in the circuit. The pin configuration is as follows: - Pin 1: Connection point for one end of the circuit - Pin 2: Connection point for the other end of the circuit

Functional Features

• Overcurrent Protection: The MF-RX135/72-2 provides protection by limiting the current flow in the circuit when an overcurrent condition is detected.
• Self-Healing: After the overcurrent condition is removed, the device resets itself and resumes normal operation.

Advantages

• Resettable: Eliminates the need for replacement after a fault condition, reducing maintenance costs.
• Fast Response: Quickly limits the current during overcurrent events, protecting sensitive components.

Disadvantages

• Limited Trip Current Range: May not be suitable for applications requiring higher trip currents.

Working Principles

The MF-RX135/72-2 operates based on the PTC effect, where its resistance increases significantly when the current exceeds the trip threshold. This increase in resistance limits the current flow, providing protection to the circuit.

Detailed Application Field Plans

The MF-RX135/72-2 is commonly used in various electronic circuits, including: - Power supplies - Battery management systems - Motor control circuits - LED lighting systems

Detailed and Complete Alternative Models

• MF-RX110/72-2: Lower hold current variant
• MF-RX160/72-2: Higher hold current variant
• MF-RX135/60-2: Lower voltage rating variant

In conclusion, the MF-RX135/72-2 is a resettable fuse with specific hold and trip current ratings, designed to provide reliable overcurrent protection in electronic circuits. Its self-healing nature and fast response make it a preferred choice for various applications in the electronics industry.
