  1、 What is fuse resistance?

  Resistors and fuses are similar in material and construction, while fuse type resistors serve both functions and can be used as resistors to protect machine equipment in case of abnormal current. Due to its dual function, the cost is reduced accordingly. Fuse resistors can be divided into: metal film fuse resistors, fuse type wound resistors, and fuse type cement resistors. There are several types of power: 1/4W, 1/2W, 1W, and 2W. As the power increases, the appearance size of the product will continue to increase.

  2、 The function of fuse resistance

  Resistors and fuses are similar in material and construction, while fuse type resistors serve both functions and can be used as resistors to protect machine equipment in case of abnormal current. Usually, the resistance of a fuse is significantly higher than that of an equally long wire, so that it can protect the circuit. If the current or voltage exceeds the rated value, the fuse will blow, causing the circuit to open, thus protecting the electrical appliances. Without a fuse, the circuit and electrical appliances are easily burned out.
