Introduction to 0224005.DRT2W

The 0224005.DRT2W is one of the most common types of fuses used for electrical systems. This type of fuse has an extremely low breaking capacity of 2 Watts. As such, this type of fuse can be used in applications with low power requirements, such as lights, audio systems, small motors, and other low power circuits.

Application Field

The 0224005.DRT2W fuse is mainly used in tightly packed electrical circuits, such as dense PCBs or in cramped control panels. It is also commonly used in power supplies, audio systems, and other low-power electronic circuits.

Working Principle

The 0224005.DRT2W is a negative temperature coefficient (NTC) device. This means that the resistance of the fuse will decrease as the temperature of the fuse increases. When an overcurrent flows through the fuse, the amount of heat generated in the fuse increases the temperature, and consequently, the resistance of the fuse lowers. This will cause increased current to flow through the fuse and eventually the fuse will “blow” and separate the circuit, making it “open”.

Advantages and Disadvantages

The 0224005.DRT2W is a versatile fuse that is great for protection against low power circuits. It also allows for a tighter pack, meaning it can provide the same protection as a larger fuse, but in a much smaller footprint. However, this type of fuse does have some disadvantages. The most significant disadvantage of the 0224005.DRT2W is its low breaking capacity, which means that it will not protect against high current loads and could be susceptible to damage in the event of an overload.

Conclusion

In conclusion, the 0224005.DRT2W fuse is a great option for low current circuits. Its low profile makes it an ideal choice for densely packed applications, while its low breaking capacity ensures that it will not be damaged by high current applications. However, its low breaking capacity does mean that it should not be used for circuits that require more protection.
