FKN300JR-73-3R9

Through Hole Resistors are components used in electrical circuits to limit current or divide voltage. The FKN300JR-73-3R9 is an example of such a resistor. This component is a three terminal, fixed value, through hole resistor with the following specifications: resistance, resistance tolerance, power rating, and temperature coefficient.

FKN300JR-73-3R9 has many applications in a variety of industries. It is commonly used for high-frequency applications such as in cell phones, computers, radios, and home entertainment systems. It can also be used in power supplies, motor drives, and precision analog designs. Its small size and high reliability make it suitable for various industrial applications where compactness is required.

The working principle of the FKN300JR-73-3R9 is based on Ohm’s law. Ohm’s law states that the current through a resistor is directly proportional to the voltage applied across it. Therefore, when a certain voltage is applied to the resistor, a corresponding amount of current will flow through it. As the current flows through the resistor, a proportionate amount of energy is dissipated in the form of heat. This heat then dissipates through the resistor\'s body and into the surrounding environment.

FKN300JR-73-3R9 is designed to have a low temperature coefficient, meaning that the resistance will remain relatively consistent even with changes in temperature. This is essential for use in environments where temperature fluctuates, as it ensures that the current through the resistor will not be affected by these changes. Additionally, the component’s high power rating makes it suitable for high-power applications.

In summary, the FKN300JR-73-3R9 is a three terminal, fixed value, through hole resistor with a low temperature coefficient and high power rating. Its small size and high reliability make it suitable for various industrial applications, and it is commonly used for high-frequency applications such as in cell phones, computers, radios, and home entertainment systems.
