MDQ-2-1/4 Fuses

Fuses are a vital part of any electrical system. They are affordable, easy to use, and provide electrical protection. The MDQ-2-1/4 fuse is a popular and widely used fuse. It is commonly used in many home, industrial, and commercial applications.The MDQ-2-1/4 fuse is a miniature fuse with a current rating of 1.1 to 2.1 amps. It has a breaking capacity of 3.2kA. The fuse is cylindrical in shape, with a length of 12.0mm and a diameter of 4.2mm. It has a base rating of 250V. The fuse is available with solder or quick connect terminals. In addition, the fuse is RoHS compliant and is available in a variety of colors.

Application Fields

The MDQ-2-1/4 is typically used in the following applications:

• Desktop computers
• Notebook computers
• Home appliances
• Industrial control circuits
• Automotive circuits
• Electronic equipment
• LED lighting

The MDQ-2-1/4 is a popular choice for home and industrial applications due to its size, current rating, and price. It is also used in many different types of lighting applications.

Working Principle

The MDQ-2-1/4 fuse operates on the principle of “current limitation”. When the current flowing through the fuse reaches the rated value, the fuse element will heat up and expand. This expansion will cause the fuse to open, thus interrupting the circuit. There are also other types of fuses available, such as time-delay fuses, which allow for a short delay before the circuit is opened.

Safety Features

Fuses provide numerous safety features. They are designed to open the circuit before the current exceeds the fuse’s rated value. This prevents damage to the electrical components in the circuit. In addition, fuses provide protection against short circuits, which are often caused by equipment malfunction or by power lines coming into contact with each other.The MDQ-2-1/4 fuse is designed to open the circuit quickly, thus providing reliable protection. It has a breaking capacity of 3.2kA, so even if a short circuit occurs, the fuse will open the circuit before it reaches damaging levels.

Summary

The MDQ-2-1/4 is a miniature cylindrical fuse with a current rating of 1.1 – 2.1 amps. It is commonly used in home and industrial applications due to its size, price, and breaking capacity. The MDQ-2-1/4 operates on the principle of current limitation, and provides protection against short circuits. It is RoHS compliant and is available in various colors.
