Through Hole Resistors

Through hole resistors are a type of passive component consisting of two terminals connected by a resistive element. H8487KDYA is a through hole resistor frequently used in many applications due to its low cost, durability, and simplicity. It is a cylindrical component with metal case, lead wires, and a resistive element.

Application Field

H8487KDYA is often used as current-limiting components. This makes it useful in applications such as power supplies, switches, circuit protection, and power supplies. It can also be used to control signals and reduce noise, and in feedback and control circuits.The H8487KDYA also finds use in high-end electronics, such as automotive and avionics systems, due to its high temperature coefficient and stability. It is also commonly used in applications with high operating temperatures, such as automated systems and robotics.

Working Principle

H8487KDYA works by allowing electrical current to flow through its terminals. As the current flows through the component, the resistance of the component increases, which creates a voltage drop across the terminals. The resistance can be adjusted by turning the resistor’s adjustment knob clockwise or counter clockwise.The resistance is also affected by temperature, with higher temperatures causing the resistance to increase. H8487KDYA is also capable of withstanding temperatures of up to 200˚C, making it suitable for high-temperature applications. The H8487KDYA also features a power rating, which is the maximum power that can be safely dissipated by the component. The power rating is often expressed as a wattage rating, which is the maximum amount of power that can be safely dissipated in a given time. For example, a 1W resistor can dissipate up to 1W of power within a given time, usually 1 minute. This power rating is based on the resistor’s ability to absorb heat and is affected by both the internal resistance and wattage rating of the resistor.

Conclusion

H8487KDYA is one of the most commonly used through hole resistors due to its low cost, durability, temperature coefficient, and stability. It is widely used in applications such as power supplies, switches, circuit protection, and power supplies. It works by allowing electrical current to flow through its terminals, and its resistance can be adjusted by turning the knob clockwise or counter clockwise. It has a power rating, which is the maximum power that can be safely dissipated by the component, and it can withstand temperatures up to 200˚C.
