MF-RX014/250U-0

Product Overview

Category

The MF-RX014/250U-0 belongs to the category of resettable fuses, commonly known as PTC (positive temperature coefficient) thermistors.

Use

It is used to protect electronic circuits from overcurrent and short-circuit conditions by limiting the flow of excessive current.

Characteristics

• Resettable: The fuse automatically resets after the fault condition is removed.
• Fast response time: Provides quick protection against overcurrent events.
• Compact size: Occupies minimal space on the circuit board.
• RoHS compliant: Meets environmental standards for hazardous substances.

Package

The MF-RX014/250U-0 is typically packaged in tape and reel format for automated assembly processes.

Essence

The essence of the MF-RX014/250U-0 lies in its ability to provide reliable overcurrent protection while offering the convenience of automatic reset functionality.

Packaging/Quantity

It is commonly available in reels containing a specified quantity, typically 2000 pieces per reel.

Specifications

• Reliable Performance: Ensures consistent protection without the need for replacement after a fault event.

Advantages and Disadvantages

Advantages

• Cost-effective alternative to traditional fuses
• Automatic reset eliminates the need for manual intervention
• Fast response time enhances circuit protection

Disadvantages

• Limited maximum voltage rating compared to some traditional fuses
• May exhibit higher resistance compared to conventional fuses

Working Principles

The MF-RX014/250U-0 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 cleared, the device's resistance decreases, allowing normal current flow.

Detailed Application Field Plans

The MF-RX014/250U-0 is widely used in various electronic applications, including: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment - Power supplies

Detailed and Complete Alternative Models

Some alternative models to the MF-RX014/250U-0 include: - MF-RX010/250U-2 - MF-RX020/250U-0 - MF-RX030/250U-0

In summary, the MF-RX014/250U-0 is a resettable fuse with fast response time, compact size, and automatic reset functionality. It provides reliable overcurrent protection and finds application in diverse electronic systems.
