Characteristics

• Resettable: The fuse automatically resets after the fault condition is removed.
• Fast response time: Provides quick protection against overcurrent events.
• Compact size: Suitable for space-constrained applications.
• RoHS compliant: Environmentally friendly construction.

Package

The MF-R015/600-A-2 is typically available in tape and reel packaging for automated assembly processes.

Essence

The essence of the MF-R015/600-A-2 lies in its ability to provide reliable overcurrent protection while offering the convenience of automatic reset functionality.

Packaging/Quantity

The product is usually packaged in reels containing a specific quantity based on industry standards.

Specifications

• Hold Current: 0.15A
• Trip Current: 0.30A
• Max Voltage: 60V
• Operating Temperature Range: -40°C to 85°C
• Resistance: <1Ω

Detailed Pin Configuration

The MF-R015/600-A-2 features a standard radial leaded package with two pins for through-hole mounting. The pinout configuration is as follows: - Pin 1: Connected to one end of the PTC thermistor element - Pin 2: Connected to the other end of the PTC thermistor element

Functional Features

• Overcurrent Protection: The device responds to overcurrent conditions by increasing its resistance, limiting the current flow and protecting the circuit.
• Automatic Reset: After the fault is cleared, the PTC thermistor returns to a low-resistance state, allowing normal operation to resume.

Advantages and Disadvantages

Advantages

• Reusability: Unlike traditional fuses, the MF-R015/600-A-2 does not require replacement after a fault event.
• Space-saving: Its compact size makes it suitable for miniaturized electronic designs.

Disadvantages

• Limited Voltage Rating: The maximum voltage rating may not be suitable for high-voltage applications.
• Temperature Sensitivity: The device's performance can be affected by ambient temperature variations.

Working Principles

The MF-R015/600-A-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, providing protection to the circuit. Once the fault is removed, the PTC thermistor cools down and returns to a low-resistance state, allowing normal operation to resume.

Detailed Application Field Plans

The MF-R015/600-A-2 is commonly used in various electronic systems, including: - Battery protection in portable devices - USB power distribution circuits - Automotive electronics - Industrial control systems

Detailed and Complete Alternative Models

• MF-R005/600-A-2: Lower hold current variant for sensitive electronics
• MF-R025/600-A-2: Higher hold current variant for more robust applications
• MF-R015/250-A-2: Lower voltage rating variant for specific voltage requirements

In conclusion, the MF-R015/600-A-2 offers reliable overcurrent protection with the added benefit of automatic reset functionality, making it a versatile choice for diverse electronic applications.
