Through Hole Resistors

Through hole resistors, also known as "discrete resistors", are an essential part of circuit boards containing components like transistors, capacitors and diodes. The resisters play an important role in controlling the current flow through the circuit. In this article, we will discuss the application field and working principle of FKN3WSJT-73-9R1, which belongs to the through hole resistor type.

Application Field

FKN3WSJT-73-9R1 through hole resistors are generally used in power factor sensing circuits, such as in solar panels, LED lights, and rechargeable batteries. They are often used to regulate the current flow through the circuit, preventing damage due to overloading.

The FKN3WSJT-73-9R1 resistors are also used in telecommunications, to protect sensitive electronic equipment from power surges and spikes. The resistor acts as an impedance, effectively creating a current-limiting path. This helps to protect the connected equipment from power surges and spikes.

FKN3WSJT-73-9R1 resistors can also be used in industrial automation applications, as they are able to survive in extreme environmental conditions. Their long-term reliability and performance make them an excellent choice for industrial applications where the environment may be constantly changing. In addition, these resistors are also suitable for automotive applications, thanks to their extreme durability and low profile.

Working Principle

FKN3WSJT-73-9R1 resistors work by converting electric current into heat energy, creating a resistance to the flow of electricity in the circuit. This prevents the current from getting too high, which can damage components or damage the circuit.

FKN3WSJT-73-9R1 resistors often contain multiple layers of metallic material, with a gap of a few micrometers between each layer. The higher the resistance value, the thicker this gap will be. When an electric current is applied to the resistor, it heats up the material, creating thermal energy. This thermal energy is converted into electrical energy, and this process causes a resistance to the current flow.

FKN3WSJT-73-9R1 resistors also contain a thermistor, which is a circuit component that can sense temperature changes. This allows the resistor to self-adjust its resistance value depending on the temperature of the environment. This is particularly useful in industrial automation applications, where the environment may be constantly changing.

In summary, FKN3WSJT-73-9R1 through hole resistors are a type of resistor that are commonly used in a wide range of industrial, automotive, and telecommunications applications. They work by converting electric current into heat energy, creating a resistance to the flow of electricity. This helps to protect sensitive electronic equipment from power surges and spikes, as well as helping to regulate the current through the circuit.
