CB2JBR390 through hole resistors are widely used in a range of applications in both the industrial and consumer markets. They are available in several different series, with various resistance values, wattages, and termination styles. In this article, we’ll discuss the application field and working principle of CB2JBR390 through hole resistors.

CB2JBR390 through hole resistors are mainly used in circuit power supply rectification, rectifier bridge output smoothing, motor speed control, voltage-current conversion and other applications. Since the resistor can reduce the amplitude of the alternating current, so that the current can reach the level that the load can bear, it can also be used as the load in the power supply circuit of other components. In addition, the CB2JBR390 resistor is a very important component in various measuring instruments and modern automatic control circuits, because it can resist the tremendous external voltage, control the voltage and current, so the regulator is also included in the resistor.

The working principle of CB2JBR390 through hole resistors is based on the principle of Joule heating. When electric current passes through the circuits, some of the electric energy is consumed as heat. The magnitude of this electric energy and the temperature of the circuit both depend on the resistance of the circuit. CB2JBR390 through hole resistors are designed to provide a specific resistance value, controlling the current in the circuit and dissipating heat.

When current passes through CB2JBR390 through hole resistors, some of the current is also consumed as heat, and some is diverted through the resistors. The electric current passing through the resistor is reduced and the voltage drop is increased. This voltage drop produces an angle current, which generates heat according to the original Joule\'s law. The heat on the resistor is dissipated through conduction and radiation.

In addition, CB2JBR390 through hole resistors also can reduce interference, improve safety, and correspondingly increase the service life of the circuit. Its widely application field is not only in power rectification and bridge output, but also in daily drive field. Its use range is very wide, and it is very popular among electronic enthusiasts.

In conclusion, CB2JBR390 through hole resistors are widely used in a range of applications. They are designed to provide a specific resistance value, controlling the current in the circuit and dissipating heat. They can be used in circuit power supply rectification, rectifier bridge output smoothing, motor speed control, voltage-current conversion, as well as to reduce interference, improve safety, and correspondingly increase the service life of the circuit.
