Product Overview

Category

The MF-R700-0-99 belongs to the category of resettable fuses or PTC (Positive Temperature Coefficient) thermistors.

Use

It is used as a protection device in electronic circuits to limit overcurrent and prevent damage to sensitive components.

Characteristics

• Resettable fuse
• High current handling capability
• Compact package
• Self-resetting feature
• Reliable overcurrent protection

Package

The MF-R700-0-99 is typically available in a surface mount package.

Essence

The essence of the MF-R700-0-99 lies in its ability to provide reliable overcurrent protection while being self-resetting, eliminating the need for replacement after a fault condition.

Packaging/Quantity

The MF-R700-0-99 is usually supplied in reels with a specific quantity per reel, typically 2000 pieces per reel.

Specifications

• Hold Current: 7A
• Trip Current: 14A
• Maximum Voltage: 30V
• Operating Temperature Range: -40°C to 85°C
• Dimensions: 3.2mm x 1.6mm x 0.8mm

Detailed Pin Configuration

The MF-R700-0-99 has two terminals for connection in the circuit. The pin configuration is as follows: - Pin 1: Connection terminal 1 - Pin 2: Connection terminal 2

Functional Features

• Overcurrent Protection: When the current exceeds the trip current, the resistance of the MF-R700-0-99 increases significantly, limiting the current flow and providing protection to the circuit.
• Self-Resetting: After the fault condition is removed, the MF-R700-0-99 returns to its low-resistance state, allowing normal operation without the need for replacement.

Advantages

• Self-resetting capability
• Reliable overcurrent protection
• Compact size
• Suitable for automated assembly processes

Disadvantages

• Limited maximum voltage rating
• Trip current may not be adjustable

Working Principles

The MF-R700-0-99 operates based on the PTC effect, where its resistance increases with temperature. When an overcurrent condition occurs, the temperature of the PTC thermistor rises, causing a significant increase in resistance, thereby limiting the current flow.

Detailed Application Field Plans

The MF-R700-0-99 is commonly used in various electronic devices and systems, including: - Power supplies - Battery packs - Automotive electronics - Industrial control systems - Consumer electronics

Detailed and Complete Alternative Models

Some alternative models to the MF-R700-0-99 include: - MF-R500-0-99 - MF-R900-0-99 - MF-R1100-0-99 - MF-R1500-0-99

In summary, the MF-R700-0-99 is a resettable fuse with high current handling capability, self-resetting feature, and compact package, making it suitable for a wide range of electronic applications requiring reliable overcurrent protection.
