MF-R400-0-15-99

Product Overview

Category

The MF-R400-0-15-99 belongs to the category of resettable fuses, also known as 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
  • Polymer-based PTC thermistor
  • Fast response time
  • Compact size
  • RoHS compliant

Package

The MF-R400-0-15-99 is typically available in tape and reel packaging for automated assembly. The quantity per reel varies based on manufacturer specifications.

Specifications

  • Hold Current: 4A
  • Trip Current: 8A
  • Maximum Voltage: 30V
  • Operating Temperature Range: -40°C to 85°C
  • Resistance: <15mΩ

Detailed Pin Configuration

The MF-R400-0-15-99 features two terminals for connection within the circuit. The pin configuration is as follows: - Pin 1: Input/Anode - Pin 2: Output/Cathode

Functional Features

  • Overcurrent Protection: When the current exceeds the trip current, the resistance of the PTC thermistor increases rapidly, limiting the current flow.
  • Automatic Reset: Upon removal of the fault condition, the PTC thermistor resets to its low-resistance state, allowing normal operation to resume.

Advantages and Disadvantages

Advantages

  • Self-recovering protection
  • Eliminates the need for replacement fuses
  • Compact design
  • Reliable overcurrent protection

Disadvantages

  • Limited voltage and current handling capabilities compared to traditional fuses
  • Slight power dissipation during overcurrent events

Working Principles

The MF-R400-0-15-99 operates based on the principle of positive temperature coefficient. As the current through the device increases, the temperature rises, causing the resistance to surge and effectively limit the current flow. Once the fault is removed, the device cools down, returning to its low-resistance state.

Detailed Application Field Plans

The MF-R400-0-15-99 is widely used in various electronic applications, including: - Power supplies - Battery packs - USB ports - Automotive electronics - Industrial control systems

Detailed and Complete Alternative Models

  • MF-R050-0-99
  • MF-R110-0-99
  • MF-R250-0-99
  • MF-R500-0-99

In summary, the MF-R400-0-15-99 resettable fuse offers reliable overcurrent protection in a compact and self-recovering package, making it an ideal choice for a wide range of electronic applications.
