H82K49DCA Through Hole Resistors: Application Field and Working PrincipleThrough hole resistors are among the oldest and most commonly used components of electrical and electronic circuits, as they have been around for centuries. Like many electronic components, through hole resistors are used to limit the current passing through a circuit, providing resistance to prevent the electrical current from fluctuating. The most familiar type of through hole resistor is the H82K49DCA. In this article, we will look at the application field and working principle of the H82K49DCA through hole resistor.The H82K49DCA through hole resistor is a type of resistor known as a flat disc-shaped resistor. It is an industrial characterisation resistor intended for use in electronic equipment that is extremely reliable in operation. It has a power rating of 5W and has a resistor value accuracy range of 0.1-500Ω. It also has a high frequency stability, and is capable of operating in temperature ranges of -55°C to +155°C, making it suitable for use in a wide range of environments.The H82K49DCA is commonly used in a variety of applications, including in telecommunications systems, aerospace and defence system, broadcasting systems, medical instruments, embedded systems, and lighting applications. It is also used in the automotive industry for a variety of applications, including to maintain a consistent current to engine sensors and prevent voltage breakdown.In addition to its various applications, the H82K49DCA also has an incredibly simple yet effective working principle. In essence, the H82K49DCA acts as a voltage divider, meaning that it limits the voltage passing through a circuit by dividing it into two, allowing the user to maintain a consistent voltage. This is accomplished by the resistor\'s resistance, which is measured in ohms. The greater the resistance, the greater the voltage division. This is beneficial for circuit protection, since the resistor prevents excess voltage from passing through and damaging the circuit components.The H82K49DCA through hole resistor is a robust and reliable component with a wide range of applications and a simple yet effective working principle. Its high power rating and wide temperature range make it suitable for a variety of industrial applications, while its emphasis on safety makes it a great choice for use in automotive applications. As one of the oldest components in the industry, the H82K49DCA continues to be one of the most reliable and cost-effective solutions for controlling voltage in electronic circuits.
