MF-MSMF050-2

Product Overview

Category

The MF-MSMF050-2 belongs to the category of resettable fuses, also known as PTC (positive temperature coefficient) fuses.

Use

It is commonly used for overcurrent protection in various electronic circuits and devices.

Characteristics

• Resettable: The fuse can automatically reset after the fault condition is removed.
• Low resistance in normal operation: Ensures minimal impact on circuit performance.
• Fast response time: Provides effective protection against overcurrent events.
• Compact package: Suitable for space-constrained applications.

Package

The MF-MSMF050-2 is typically available in surface mount packages, making it suitable for automated assembly processes.

Essence

The essence of the MF-MSMF050-2 lies in its ability to provide reliable overcurrent protection while offering the convenience of automatic reset functionality.

Packaging/Quantity

The fuse is usually supplied in reels or tape and reel packaging, with quantities varying based on manufacturer specifications.

Specifications

• Voltage Rating: Typically rated for 6V to 60V
• Current Rating: Ranges from 50mA to 2A
• Operating Temperature: -40°C to 85°C
• Hold Current: The maximum current that the fuse can carry without tripping
• Trip Current: The current at which the fuse trips and enters a high-resistance state

Detailed Pin Configuration

The MF-MSMF050-2 features a standard two-pin configuration, with no polarity considerations. It is important to ensure proper orientation during installation to maintain the intended circuit protection.

Functional Features

• Overcurrent Protection: Safeguards the circuit by limiting the current during abnormal conditions.
• Automatic Reset: Restores the circuit to normal operation once the fault is cleared.
• Low Resistance: Maintains low voltage drop during normal operation to minimize power loss.

Advantages and Disadvantages

Advantages

• Resettable nature increases product longevity and reduces maintenance requirements.
• Fast response time provides effective protection against transient overcurrent events.
• Compact size makes it suitable for miniaturized electronic designs.

Disadvantages

• Limited hold current compared to traditional fuses.
• Trip time may vary based on ambient temperature and operating conditions.

Working Principles

The MF-MSMF050-2 operates based on the PTC effect, where its resistance increases significantly when subjected to overcurrent conditions. This rise in resistance limits the current flow, protecting the circuit. Once the fault is removed, the device cools down and returns to its low-resistance state.

Detailed Application Field Plans

The MF-MSMF050-2 is widely used in: - Consumer electronics - Automotive electronics - Industrial control systems - Telecommunications equipment - Power supplies

Detailed and Complete Alternative Models

• Bourns MF-R050
