MF-R400-AP-99

Product Overview

Category

The MF-R400-AP-99 belongs to the category of resettable fuses.

Use

It is used for overcurrent protection in various electronic circuits and devices.

Characteristics

  • Resettable
  • Fast response time
  • Compact size
  • Reliable overcurrent protection

Package

The MF-R400-AP-99 is typically available in a tape and reel packaging, with a quantity of 3000 units per reel.

Essence

The essence of the MF-R400-AP-99 lies in its ability to provide reliable overcurrent protection while being resettable, thus offering longevity and cost-effectiveness.

Specifications

  • Maximum Voltage: 30V
  • Hold Current: 4A
  • Trip Current: 8A
  • Operating Temperature Range: -40°C to 85°C
  • Dimensions: 3.2mm x 1.6mm x 0.9mm

Detailed Pin Configuration

The MF-R400-AP-99 has two pins, one for input and the other for output. The pinout configuration is as follows: - Pin 1 (Input): Connected to the circuit requiring overcurrent protection - Pin 2 (Output): Connected to the rest of the circuit after the overcurrent protection

Functional Features

  • Overcurrent Protection: Automatically trips and disconnects the circuit in case of overcurrent conditions.
  • Resettable: Once the fault condition is removed, the fuse resets itself, allowing the circuit to resume normal operation.

Advantages

  • Longevity: Resettable feature extends the lifespan of the fuse.
  • Cost-Effectiveness: Eliminates the need for frequent replacement.
  • Space-Saving: Compact size makes it suitable for small electronic devices and circuits.

Disadvantages

  • Limited Voltage Rating: Suitable for low voltage applications only.
  • Trip Time: May have a slightly longer trip time compared to non-resettable fuses.

Working Principles

The MF-R400-AP-99 operates based on the principle of positive temperature coefficient (PTC). When an overcurrent condition occurs, the resistance of the PTC material increases, leading to the disconnection of the circuit. Once the fault is removed, the PTC material cools down, and the resistance decreases, allowing the circuit to be reconnected.

Detailed Application Field Plans

The MF-R400-AP-99 is commonly used in: - Consumer electronics - Automotive electronics - Industrial control systems - Power supplies - Battery management systems

Detailed and Complete Alternative Models

Some alternative models to the MF-R400-AP-99 include: - MF-R250-AP-99 - MF-R500-AP-99 - MF-R600-AP-99 - MF-R800-AP-99

In summary, the MF-R400-AP-99 is a resettable fuse that provides reliable overcurrent protection in various electronic circuits and devices. Its compact size, resettable nature, and fast response time make it a popular choice for applications requiring dependable overcurrent protection.
