Through hole resistors are one of the most commonly used components in electronics due to their relatively low cost and high reliability. The FKN3WSJR-73-1R is a type of through-hole resistor that is ideal for high-power applications involving large currents. This article will discuss the FKN3WSJR-73-1R’s application fields and working principle.

The FKN3WSJR-73-1R has a power rating of 73 watts, making it well-suited for high-power applications. It is designed for use in high-current circuits with a maximum current rating of 2 A. The FKN3WSJR-73-1R also has a high voltage rating of 1 kV, making it suitable for circuits with high voltage levels. The resistor has a maximum operating temperature of 125 °C, making it suitable for use in high temperature environments.

The FKN3WSJR-73-1R has a very low temperature coefficient of resistance, which means that its resistance remains relatively constant over a wide range of temperatures. This makes the FKN3WSJR-73-1R ideal for circuits that require a high degree of accuracy and stability. The resistor also offers excellent high-frequency performance, making it suitable for use in circuits with high-frequency components.

The FKN3WSJR-73-1R has a wide range of application fields, including power supplies, automotive electronics, and other high-power circuits. The resistor can also be used in power amplifiers, motor control circuits, and other applications that require high current and voltage levels. The resistor is also ideal for pulse generation and precision circuit timing applications.

The FKN3WSJR-73-1R is a non-inductive resistor, which means that it does not induce electromagnetic fields. This makes the FKN3WSJR-73-1R well-suited for use in circuits where power interference must be minimized. The resistor can also be used in high-temperature circuits where high thermal conductivity is required.

The working principle of the FKN3WSJR-73-1R is relatively straightforward. The resistor is basically a semiconductor made up of a resistor element, a dielectric layer, and a protective ceramic body. When a current is applied to the resistor, the resistance of the resistor element changes, which creates a voltage drop across the resistor. This voltage drop is proportional to the current applied to the resistor and is directly proportional to the resistance of the resistor element. The voltage drop is what is used to control the flow of current through the resistor.

In summary, the FKN3WSJR-73-1R is a type of through-hole resistor that is ideal for high-power applications involving large currents. The resistor has a power rating of 73 watts, a maximum current rating of 2 A, and a maximum operating temperature of 125 °C. The resistor also has a low temperature coefficient of resistance, making it suitable for circuits that require a high degree of accuracy and stability. Furthermore, the resistor is non-inductive, making it suitable for use in circuits where power interference must be minimized. Finally, the working principle of the FKN3WSJR-73-1R is relatively straightforward, with the voltage drop across the resistor being proportional to the current applied to it.
