Through-hole resistors are resistors that are accessible from one side of a board. They are the most commonly used type of discrete parts in electronic circuits, mainly because they have the ability to be easily connected to printed circuit boards (PCBs). This article will focus on the PSM500JB-470R through-hole resistor, and its application field and working principle.

What is a Through-Hole Resistor?

A through-hole resistor is a type of resistor that can be soldered directly onto a printed circuit board (PCB). It consists of a metal ‘spine’ and a number of metal clips that make up the resistor element. The resistive element is usually a ceramic material, such as carbon or other ceramic materials, that is coated with a non-conductive material to insulate the resistor. This type of resistor has the advantage of being relatively inexpensive and easy to work with. It is typically used in applications where the current is low, which is why it is commonly used in electronic circuits.

The PSM500JB-470R through-hole resistor is a resistor manufactured by Kingbright. It is a surface mount resistor and is designed to withstand up to 500 volts. It has a resistance value of 470 ohms and is rated for a power dissipation of 0.75 watts. The part is constructed using a thermally enhanced mold and is RoHS compliant, meaning it has been designed to meet certain environmental and safety standards.

Application Field of the PSM500JB-470R Through-Hole Resistor

The PSM500JB-470R through-hole resistor is commonly used in applications that require high voltage tolerance and low power dissipation. It is often used in power divider networks that will be exposed to high voltages, such as power inverters and motor controllers. It is also well-suited for applications that require a high level of accuracy and reliability, such as in motor control circuits. The part is also capable of handling a wide range of temperatures, making it ideal for automotive and military applications.

Working Principle of the PSM500JB-470R Through-Hole Resistor

The PSM500JB-470R through-hole resistor works by increasing the resistance of the circuit it is connected to. The resistor is composed of a metal ‘spine’ and several metal clips so that the resistor element can be easily soldered onto the circuit board. The resistor is then connected to the power supply, and the current flowing through the resistor is affected by the resistance value. As the current passes through the resistor, it dissipates as heat. The heat is then dissipated to the environment by forced convection or radiation.

The resistance of the PSM500JB-470R through-hole resistor can be adjusted in order to affect the voltage and current in a given circuit. This process is known as potentiometry, and can be used to adjust the amplitude and frequency of signals, or to control the speed of a motor.

Conclusion

The PSM500JB-470R through-hole resistor is a resistor manufactured by Kingbright. It is a surface mount resistor and is designed to withstand up to 500 volts. It has a resistance value of 470 ohms and is rated for a power dissipation of 0.75 watts. The part is commonly used in applications that require high voltage tolerance and low power dissipation. Its working principle is based on the principle of increasing the resistance of the circuit it is connected to in order to dissipate heat and adjust the voltage and current in a given circuit.
