Through Hole Resistors

Through hole resistors are components used in a variety of circuit designs, providing electrical resistance to reduce or modify current flow. The FKN2WSJR-73-0R56 resistor is a commonly used through hole resistor for providing resistor-based solutions in a variety of applications. This article will explore the application field and working principle of the FKN2WSJR-73-0R56 resistor.

Applications

The FKN2WSJR-73-0R56 is a through hole resistor used mainly for high voltage applications, particularly those with AC and high DC voltages. This is due to its high insulation resistance and its ability to cope with high currents and surge events. It has a high current carrying capacity, up to 50 Amps, making it a good choice for use in both low and high voltage applications.

Due to its ability to handle high voltages, the FKN2WSJR-73-0R56 is often chosen as the primary form of resistor in applications such as circuit protection, current limitation, and high power amplification, among other uses. Specifically, it is commonly used in microwave ovens, air conditioners, medical devices, and other high-power applications to provide protection and control of the electrical system. Because of its high insulation resistance, it is also used in high voltage direct current (HVDC) systems.

Design and Working Principle

The design of the FKN2WSJR-73-0R56 resistor consists of two main components: a coil and a heat-sensitive ceramic element. The coil is typically made from a highly conductive material such as copper or aluminum, and it is wrapped around the heat-sensitive ceramic element. The coil is then connected to the power source via a pair of wires, and the resistor is then secured in place. The ceramic element acts as a resistor and is designed to absorb heat energy when current is flowing through the coil.

When the resistor is placed into the circuit, it begins to limit the current flow by providing resistance. The coil is designed to act as an inductor, which helps to dampen the current flow and reduce surges. The heat-sensitive ceramic element is designed to absorb the unwanted heat generated by the current flow through the coil. As more current passes through the coil, more heat is absorbed by the ceramic element, which in turn reduces the resistance of the resistor. This allows more current to pass through the coil, while still providing protection and control of the system.

Conclusion

The FKN2WSJR-73-0R56 is a commonly used through hole resistor, mainly used in high voltage applications due to its ability to handle high currents and surge events. It is typically used for circuit protection, current limitation, and high power amplification. Its design consists of a coil made from a highly conductive material and a heat-sensitive ceramic element. The ceramic element absorbs the heat generated by current flow, and the coil acts as an inductor to dampen the current flow and reduce surges. By providing resistance in a circuit, the FKN2WSJR-73-0R56 is an essential component in the protection and control of any high power system.
