DFJ-80-W Application Field and Working Principle

DFJ-80-W, a fast-acting electrical specialty fuse, is widely used in industrial and automotive electronic circuits, consumer electronics, military equipment, office equipment, and other fields. This fuse is designed to prevent circuit overcurrent, thereby making people\'s work easier and safer. The working principle of DFJ-80-W can be discussed through a better understanding of its structure and material.

Structure

DFJ-80-W is composed of two parts: a fuse body and a fuse wire. The fuse body is made of a flame-retardant thermoplastic material, which is designed to contain and protect the fuse wire. The fuse wire is made of Zinc-coated iron wires, which are designed to burst quickly in an overload or short-circuit current situation.

Material

The body of DFJ-80-W is made with UL 94V-0 thermoplastic material, which helps to prevent outside objects from causing a fire by providing a destructive path for them. The fuse wire is made of Zinc-coated iron, which gives the fuse excellent electrical and mechanical characteristics and allows it to detonate quickly when an overload or short-circuit current exceeds its designated rating.

Application Field

DFJ-80-W is widely used in many areas. It can be used as an electric fuse in industrial and automotive electronic circuits, consumer electronics, military equipment, office equipment, and other fields. It is also used as an auxiliary safety device for guardrails and power panels. In addition, it can be applied as a resistor in low-voltage circuits for temperature compensation and voltage regulation.

Working Principle

When the current in the circuit exceeds the specified value, DFJ-80-W can quickly respond. The high current causes the fuse wire to heat up and vaporize, thus forming a gap between the two parts of the body. This breaks the circuit, quickly limiting the current to the rated value and protecting the circuit from being damaged by overload or short-circuit current. Once the fuse is blown, it must be replaced, otherwise it will cause an interruption of the circuit.

Conclusion

DFJ-80-W is a fast-acting electrical special fuse that is widely used for safety and protection purposes in many areas. Its UL94V-0 flame-retardant material helps to protect the fuse body form outside objects, while its Zinc-coated iron fuse wire helps to quickly respond in an overload or short-circuit current situation. Its rated current value is an important factor to consider when you use it. It can help to protect the circuit from being damaged by overcurrent or short-circuit current.
