MF-R500-2

Product Overview

Category

The MF-R500-2 belongs to the category of resettable fuses, also 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 current in the event of a fault.

Characteristics

• Resettable: The MF-R500-2 can return to its normal state after the fault condition is removed.
• Fast-acting: It responds quickly to overcurrent conditions, providing rapid protection to the circuit.
• Compact package: The device is designed in a small form factor, suitable for various electronic applications.
• Reliable performance: Offers consistent and reliable protection against overcurrent events.

Package

The MF-R500-2 is typically available in tape and reel packaging for automated assembly processes. It is also offered in bulk packaging for manual assembly requirements.

Essence

The essence of the MF-R500-2 lies in its ability to safeguard electronic circuits from damage caused by overcurrent situations, thereby enhancing the reliability and longevity of electronic devices.

Packaging/Quantity

The MF-R500-2 is commonly packaged in reels containing 2000 units for automated assembly. Bulk packaging options are available for smaller quantities.

Specifications

• Hold Current: 5A
• Trip Current: 10A
• Voltage Rating: 30V
• Operating Temperature Range: -40°C to 85°C
• Maximum Time-to-Trip: 20 seconds at 25A
• Resistance: <0.1Ω

Detailed Pin Configuration

The MF-R500-2 features a two-pin configuration, with no polarity considerations. Pin 1 is the input terminal, while pin 2 serves as the output terminal.

Functional Features

• Overcurrent Protection: The MF-R500-2 limits the current flow in the circuit when an overcurrent condition is detected, protecting the connected components.
• Resettable Operation: After the fault is cleared, the device automatically resets, restoring the circuit to its normal operation.
• Fast Response: Rapid reaction to overcurrent events ensures minimal disruption to the circuit's functionality.

Advantages

• Reusability: Unlike traditional fuses, the MF-R500-2 does not require replacement after a fault, offering cost savings and convenience.
• Space-saving: Its compact design makes it suitable for applications with space constraints.
• Reliability: Provides consistent and reliable protection against overcurrent situations, contributing to the overall reliability of the electronic system.

Disadvantages

• Limited Voltage Rating: The voltage rating of 30V may restrict its use in high-voltage applications.
• Trip Time Variability: In certain conditions, the trip time may vary, requiring careful consideration in critical applications.

Working Principles

The MF-R500-2 operates based on the PTC effect, where its resistance increases significantly when subjected to overcurrent, limiting the current flow through the circuit. Once the fault is removed, the device cools down, returning to its low-resistance state.

Detailed Application Field Plans

The MF-R500-2 finds extensive application in various electronic systems, including: - Consumer electronics - Automotive electronics - Industrial control systems - Power supplies - Battery management systems

Detailed and Complete Alternative Models

• MF-R050: Lower hold and trip currents, suitable for low-power applications.
• MF-R110: Higher voltage rating and hold current, ideal for applications with higher voltage requirements.
• MF-R700: Higher hold and trip currents, catering to heavy-duty circuit protection needs.

In conclusion, the MF-R500-2 offers reliable and resettable overcurrent protection for a wide range of electronic applications, making it a valuable component in ensuring the longevity and safety of electronic systems.
