067206.5DRT4P

Fuses

Fuses are a common and crucial device that protect electrical circuits from damage due to overcurrent. In the backdrop of traditional fuse, the 067206.5DRT4P fuse is specially designed for low-voltage and signal loads. It is a radially leaded surface mount fuse, suitable for temperatures up to +125° C.

Application Field

The 067206.5DRT4P is mainly used for overcurrent protection in audio, signal, communication, consumer and industrial electronic, etc. It is also suitable for automotive and airplane application.

It can also be used in telecommunications equipment, household appliances, computers, TV sets, switchboards, etc. It can protect circuits and devices from overvoltage, overcurrent, short circuits and much more.

Working Principle

The 067206.5DRT4P fuse plays the role of circuit breaker when overcurrent passes through it. Generally speaking, when the current beyonds its rated current limit, its resistance will increase significantly and the electric circuit containing it will go into an open state. So the current in the circuit will be shut off to protect the circuit and devices from damage.

The 067206.5DRT4P fuse is equipped with two metal wires. One is being heated due to the current passes through it. When the current reaches the rated current limit, the metal wire will melt and the circuit will be open.

In some circuits, such as audio, signal and communication circuits, a metal inserted in the metal wire can reduce the melting time of the fuse, and thus to reduce the damage caused by the overvoltage and overcurrent.

Conclusion

The 067206.5DRT4P fuse has been widely applied in audio, signal, communication, consumer and industrial electronic, automotive, airplane, telecommunications equipment and other devices. Its working principle is simple but efficient, which can protect the circuits and devices from overvoltage, overcurrent, short circuits and much more.
