A resistor is an electronic component that acts as a resistance in a circuit and can suppress the flow of electricity.
There are a variety of products available for various applications, including resistors that can handle resistance values of up to 100 omega.
They can handle high resistance values and narrow deviations, which can improve reliability and suppress circuit signal variations.
Resistors regulate the amount of electricity flowing through a circuit in a controlled manner and help the circuit operate properly. High-voltage resistors are suitable for equipment and applications with high-voltage circuits because they are resistors that can handle high voltages.
Major equipment and applications include high-voltage power supplies, X-ray power supplies, and various high-voltage devices such as printers, copiers, automobiles, air conditioners, lighting, electrostatic discharge, lasers, and power supplies for plasma displays.
A resistor is an electronic component that can suppress the flow of electricity, but by using as a material a conductor with a high resistivity among conductors.
High-voltage resistors are specialized for high voltage among resistors, so the parts used can handle high voltage by maintaining high insulation properties.
Based on a substrate and insulator, the resistor consists of a resistive element, a protective coating to protect the element, an external electrode, and an internal electrode connected to the element.
Alumina insulators are mainly used for the insulators.
Each part of the resistor has a structure that can withstand high voltages, making the resistor as a whole capable of withstanding high voltages.
Since the terminal part is the connection point of the resistor and receives voltage and current, a structure and material that does not affect the characteristics of the resistive element are used.
In addition, there are patterns of resistive elements, forming shapes that can withstand high voltages, such as solid, meander, and serpentine.
