NKN3WSJR-73-4R7

Through Hole Resistors are fixed components primarily designed for alternating current applications. They are made up of one to two coils of a metal wire, wrapped around a core of ceramic, glass, or a non-conducting material. The wire is usually composed of copper, aluminum, nickel/iron alloys, or silver-plated copper. The metal wire is wound to form a resistance element. These resistors are also known as wire-wound resistors and are highly reliable for use in any AC circuit.

NKN3WSJR-73-4R7 is a variable resistor with a coil winding resistance of 73 ohms and a core diameter of 4.7 mm. As an Through Hole Resistor, it is intended for use in various AC applications. NKN3WSJR-73-4R7 can dissipate power up to 4 Watts and can tolerate a voltage of up to 2kV AC.

The working principle of this Through Hole Resistor involves passing a current through the metal wires, creating a magnetic field. The magnitude of the voltage that passes through the resistor influences the strength of the magnetic field, which determines the resistance of the resistor. When the voltage is low, the resistance is high and vice versa. This is one of the most significant reasons why this type of resistor is particularly suited to AC applications, as it is able to adjust its resistance depending on how much voltage is present.

NKN3WSJR-73-4R7 has a wide variety of applications. It is commonly used in high power AC applications where precise adjustment of current is essential. Examples include industrial controls, motor speed control and power supplies. It can also be used in more general circuits, such as power amplifiers, audio amplifiers, home entertainment systems and precision timing circuits. It can also be used for testing and measurement applications.

In conclusion, NKN3WSJR-73-4R7 is a Through Hole Resistor that is ideal for AC applications where precise adjustment of current is required. Its resistance is adjustable according to the amount of voltage present. It can endure high power up to 4 Watts and tolerate up to 2kV AC. It has many applications in numerous areas, with the most common ones being power supplies, motor speed control, industrial controls, power amplifiers, audio amplifiers, home entertainment systems, precision timing circuits and testing and measurement equipment.
