MDQ-6 Application Field and Working Principle

The MDQ-6 is an eight-element radial-leaded fuse designed for overcurrent protection in electronic and electromechanical circuits. It is designed to provide protection against over-current, short-circuiting, and over-voltage protection (OVP). The fuse has a temperature rating of 125°C, and its rated current is 6A. It is designed to fit a variety of circuit boards, and is UL listed.

Applications

The MDQ-6 radial-leaded fuse is used in a variety of circuits, including:

  • Automotive and industrial control circuits
  • Power supplies
  • Communications applications
  • Photovoltaic applications
  • Electronic equipment

Working Principle

When a circuit exceeds its rated current, the MDQ-6 fuse will energize, causing the fuse element to expand rapidly and create an arc between the contact points. The arc is then extinguished by quenching, which is the process of dispersing it in a controlled manner. The quenching process also transfers heat to the surrounding air, cooling the components and improving the efficiency of the device. When the current is reduced to a safe level, the MDQ-6 fuse will reset itself. When the reset occurs, the arc path between the contact points is broken, and the temperature of the surrounding area drops to safe levels. In order to avoid thermal damage, the fuse is designed with a rated current that is slightly lower than the maximum current of the circuit it is protecting.

Advantages

The MDQ-6 fuse provides several advantages, such as:

  • High current rating
  • High temperature rating
  • Resettable
  • UL listed
  • Compact size
  • Wide range of applications

Disadvantages

The MDQ-6 fuse does have some disadvantages, such as:

  • Limitations on use when the ambient temperature is higher than 125°C
  • Difficult to replace
  • Inefficient quenching process
  • Low arc voltage rating

Conclusion

The MDQ-6 fuse is an eight-element radial-leaded fuse designed for overcurrent protection in electronic and electromechanical circuits. It is designed to provide protection against over-current, short-circuiting, and over-voltage protection (OVP). The fuse is UL listed, and offers a wide range of applications in automotive, industrial, power supplies, communications, photovoltaic and other electronic equipment. The fuse has a temperature rating of 125°C, and its rated current is 6A. The MDQ-6 fuse offers some advantages, such as high current rating, high temperature rating, resettable, compact size and a wide range of applications. On the other hand, it has some limitations such as the limitations on use when the ambient temperature is higher than 125°C, difficulties in replacing the fuse, inefficient quenching process, and low arc voltage rating.
