Through Hole Resistors are passive electronic components that are used to limit current and help to control voltage in a circuit. The NKN200JR-73-0R82 is a type of through hole resistor used to provide a very precise resistance. This article will look at the application field and working principle of this component.

Application Field

NKN200JR-73-0R82 is a through hole resistor used mostly in sensitive light detection circuits, low-end digital circuits, and high-frequency circuits. In light detection circuits, the resistor helps to reduce the sensitivity of light-emitting diodes (LEDs), resulting in a more accurate detection of light levels. In digital circuits, the resistor helps to limit fault currents in sensitive semiconductor devices, preventing them from being damaged. Finally, in high-frequency circuits, this resistor is used to attenuate signals, reduce interference, and dissipate power.

Working Principle

The NKN200JR-73-0R82 through hole resistor works in the same way as all other resistors. It is composed of a conductor, such as metal or carbon, that has a specific amount of resistance. When current flows through it, some energy is converted into heat and dissipated into the air. The amount of current that the resistor can handle is known as its "power-rating" and is typically rated in milliamps (mA). The resistor\'s resistance can also be varied by varying the temperature of its conductor, making this type of resistor particularly useful in sensor systems.

In addition to working to attenuate signals, reduce interference, and dissipate power, the NKN200JR-73-0R82 is designed to provide superior precision. The tolerance of this resistor is 0.5% compared to the industry-standard 10-20%. This makes it ideal for applications that require very precise resistance values, such as light detection circuits, as any change in resistance will be accurately detected and can be used to adjust the sensitivity of the circuit accordingly.

Conclusion

The NKN200JR-73-0R82 is a through hole resistor used in a variety of applications, from light detection circuits to high-frequency circuits. Due to its precise resistance tolerance of 0.5%, it is an excellent choice for applications requiring very precise resistances. The working principle of this resistor is the same as any other resistor—by dissipating energy as heat—but its precision makes it a superior choice for many applications.
