MF-R900-0-003

Product Overview

Category

The MF-R900-0-003 belongs to the category of resettable fuses, also known as PTC (positive temperature coefficient) thermistors.

Use

These resettable fuses are commonly used in electronic circuits to protect against overcurrent and short-circuit conditions.

Characteristics

• Resettable: The MF-R900-0-003 can return to its normal state after the fault condition is removed.
• Package: The fuse is typically housed in a small, surface-mount package.
• Essence: It provides reliable overcurrent protection for electronic devices.
• Packaging/Quantity: The MF-R900-0-003 is usually packaged in reels or trays, with varying quantities depending on the manufacturer.

Specifications

• Hold Current: 9A
• Maximum Voltage: 30V
• Trip Current: 18A
• Operating Temperature: -40°C to 85°C
• Resistance: <0.01Ω

Detailed Pin Configuration

The MF-R900-0-003 typically has two pins for connection in the circuit. The pin configuration may vary slightly based on the manufacturer's specifications.

Functional Features

• Overcurrent Protection: The fuse responds to overcurrent conditions by increasing its resistance, limiting the current flow.
• Resettable Operation: After the fault is cleared, the fuse returns to its low-resistance state, allowing normal operation to resume.

Advantages and Disadvantages

Advantages

• Resettable functionality increases the lifespan of the fuse.
• Provides reliable protection against overcurrent and short-circuit events.

Disadvantages

• Higher initial cost compared to traditional fuses.
• Limited maximum voltage and hold current ratings.

Working Principles

The MF-R900-0-003 operates based on the PTC effect, where its resistance increases significantly when exposed to high currents, effectively limiting the current flow through the circuit.

Detailed Application Field Plans

The MF-R900-0-003 is widely used in various electronic devices and systems, including: - Power supplies - Battery packs - Automotive electronics - Industrial control systems

Detailed and Complete Alternative Models

• MF-R700-0-003
