Through Hole Resistors

HHV2WSFT-73-2M2 through-hole resistor is a special type of resistors made up of small wire wound up along an ceramic core and is available in a wide variety of sizes and shapes suitable for various applications. It is designed for use in high-voltage applications, such as with appliances, batteries, motors, and harsh environments where the resistor needs to handle high temperature fluctuations. Different types of through-hole resistor are used in different applications, depending on the voltage being handled.

Application Field

As mentioned above, the HHV2WSFT-73-2M2 through-hole resistor is used in a variety of applications. The high-voltage resistors are used in high-voltage electric motors, such as electric vehicles, forklifts, escalators, and automated production lines. The resistors are also used in digital high voltage circuits, such as integrated circuits, printed circuit boards, and sensors. They can also be used in power supplies and telecommunications equipment. Because the size and performance of the resistors depend on its copper coated surface, its use also extends to the laser, welding, and heat sealing industries.

Working Principle

Through-hole resistors are widely used due to their simple structure and convenient installation. The resistor is composed of a ceramic or aluminum core, a copper coating, and an insulator that encloses the core. The copper coating serves as an electrical conductor, allowing electrical current to flow from one end of the resistor to the other. The thickness and size of the copper coating determine the resistance of the resistor. The copper coating is usually protected by a sheath of quartz glass to prevent wear, breaking, erosion, and other damage.

The copper coating is wound around the ceramic or aluminum core according to certain rules. A coating with a higher number of windings has a lower resistance than a coating with a lower number of windings. The number of layers of windings also affects the resistance. When multiple layers of windings are used, the resistance is lower than a single layer of windings. Additionally, the size of the windings will also change the resistance levels.

When electricity runs through this structure, the factors mentioned previously determine how current flows through the resistor. The resistors can handle high voltage fluctuations, enabling them to be used in various applications.
