Through-hole resistors, such as the H81K47DZA, are components used in the electronics industry to reduce or control the current flowing through an electrical component. A resistor works by restricting the flow of current and in so doing, changing the voltage in the circuit. This action creates the much needed resistance in a circuit.

There are two main types of resistors. These are fixed resistors and variable resistors. Fixed resistors can be either through-hole resistors like the H81K47DZA or surface-mount resistors. Variable resistors, on the other hand, have an adjustable resistance value that allows them to be set to different resistances. Examples of variable resistors are adjustable potentiometers, rheostats and trimmers.

The H81K47DZA is an example of a through hole variable resistor. It is an axial leaded resistor, meaning that its leads come directly out of both ends of the resistive element. The value of the resistor is usually marked with a colour band or printed on the case of the component, usually indicating the ohmic value. A wide variety of resistor values are available from several manufacturers, and makes choosing the right resistor for your application much easier.

The lead spacing of the H81K47DZA can vary, with some having a distance of 5mm and others having a distance of 12mm between leads. The resistor can be mounted in two or three different ways, accommodating up to three axial leads. A bendable axial lead is also available for additional mounting options.

In terms of application fields, through-hole resistors like the H81K47DZA are typically used in a wide range of applications, including basic circuit protection, circuit design, power supplies, signal conditioning, signal conditioning, RC (radio-controlled) toys and robots, and automotive electronics.

The performance of the H81K47DZA through-hole resistor depends on its operating temperature, voltage, supply current, and other factors such as ambient temperature and humidity. Its performance is typically rated in terms of its power rating, its maximum operating temperature, and its maximum surge current. All of these factors should be taken into consideration when choosing the right resistor for the application.

The working principle of a through-hole resistor is fairly simple. When current passes through the resistor, the resistance created generates a voltage drop across its leads, something which ultimately results in the desired reductions in the flow of current.

In conclusion, through-hole resistors like the H81K47DZA are extremely versatile and can be used to reduce or control the current flowing through an electrical component. With the right parameters, the H81K47DZA can be applied in a wide variety of application fields as well as provide the necessary resistance in a circuit. Its ability to withstand a wide range of variable temperatures, voltages, and currents also adds to its versatility.
