Through Hole Resistors are a common type of component that can be found in almost any electronic device. They are used to control and limit the amount of current in a circuit by providing resistance to current flow. The NKN200JR-73-2R is a through hole resistor used in many electronic systems, and understanding its design and operating principles is important to enable its effective use in an application.

The NKN200JR-73-2R is a standard carbon film resistor, with a power rating of 200mW and a tolerance of ± 5%. It operates over a wide temperature range of -55°C to +125°C. The resistance values of the resistor range from 2.2 ohms to 1.47 million ohms and it can handle up to 9 amps of current. Due to its ability to withstand high temperatures and large amounts of current, it is often used in high power applications such as power supplies and motor controllers.

The NKN200JR-73-2R is constructed using two layers of metal strips, one layer of which is coated with a thin layer of resistive carbon film. The other layer of metal strips is connected to a soldered-on lead frame that is cut to the desired resistance value. The carbon film provides the majority of the resistor\'s resistive value, while the lead frame provides the remainder of the value.

The working principle behind the NKN200JR-73-2R is fairly straightforward. When a current passes through the resistor, the carbon film heats up, creating resistance to the current flow. The resistor will limit the amount of current that can pass through it depending on the amount of resistance it provides. This resistance is determined by the combination of the carbon film and the lead frame. As the current increases, the resistor will heat up more, increasing its resistance and thereby limiting the amount of current that can be passed through it.

The NKN200JR-73-2R is a popular choice for applications where high current or temperature is a concern. It is used in a wide variety of systems, such as LED drivers, motor controllers, power supplies, and in automotive and medical applications. Due to its wide range of resistance values, it can be used in a variety of different circuits.

The NKN200JR-73-2R is a versatile and reliable component that is suitable for a range of applications. Knowing its design and operating principles is key in order to make the most effective use of it in any given application. Understanding the basics of Through Hole Resistors is essential for any electronic designer, and the NKN200JR-73-2R is an excellent choice for high current and temperature applications.
