HIES308461R0012 2.5Ω 5000V 100W High voltage resistor

A high-voltage resistor is an electronic component primarily used to limit current at high voltages. It is

usually composed of materials such as metal oxides, ceramics or carbon, which have special properties that

allow high-voltage resistors to effectively limit current in high-voltage environments. The working principle of a

high-voltage resistor is based on Ohm’s law, which states that when the voltage between two ports increases, the

current passing through the resistor decreases. Therefore, high-voltage resistors can help the circuit

reach a safe voltage level and limit the current to an acceptable range.

The high-voltage resistor mainly plays the role of voltage division and shunt in the circuit, and for the signal,

whether it is AC or DC signal, it can pass through the resistor. Its high resistance value and high voltage

resistance enable it to be used as a voltage divider and a drain resistor in high-voltage devices, usually in the

operating voltage range of 10~100kV. In addition, the high voltage resistor also has a certain power

carrying capacity, which can disperse the power in the circuit to a certain extent.

High voltage resistors are widely used in many fields, such as industrial robots, laser cutting machines, CNC

machine tools and so on. In industrial robots, high-voltage resistors are used to limit the current in the circuit,

ensure the safety performance of the robot, and provide electrical isolation and lightning protection. In the laser

cutting machine, the high voltage resistance is used to control the stability of the optical path and the stability

of the circuit, thereby improving the cutting accuracy and quality. In CNC machine tools, high-voltage resistors

are used to limit the current size, ensure the safety performance of the machine tool, and control the stability

of the circuit in the machine tool to improve the machining accuracy and stability.

In general, a high-voltage resistor is an important electronic component that works in a high-voltage environment, and

its high resistance value and high voltage tolerance enable it to effectively protect circuits and other electronic components from damage.
