Through Hole Resistors

A through-hole resistor, also known as a through-hole or lug resistor, is a type of resistor which is mounted on a PCB (Printed Circuit Board) with its terminals passing through the board from one side to the other making contact with the drilled holes or lugs on the board. This type of resistor design is more robust compared to its surface-mount counterpart, as the leads provide a sturdy, reliable connection within the PCB. The NKN2WSJR-73-3R3 is one such through-hole resistor and offers a wealth of features for its application field and working principle.Application Field

The NKN2WSJR-73-3R3 is a high wattage commercial grade resistor with an operating temperature range of -55° C to +125° C. It is designed for use in a wide range of applications such as DC-DC converters, motor drives, lighting controls, and the like. Due to its robust construction it is also suitable for high shock/vibration applications, hazardous locations and limited power conditions.Working Principle

The NKN2WSJR-73-3R3 is a fixed resistor whose primary focus is to reduce the current or voltage passing through a circuit. Its ability to do so is based on the principle of Ohm’s Law (V = I * R), wherein a given quantity of current (I) is reduced by a fixed amount when it passes through a fixed resistor (R). The NKN2WSJR-73-3R3 offers superior power rating, frequency range and power rating for current handling of up to 50A, making it an ideal choice for a range of high wattage applications.The NKN2WSJR-73-3R3 has a very low thermal resistance which helps dissipate heat efficiently. The surface-mountable housing also helps ensure that the heat is quickly and evenly distributed across the component. This reduces the danger of thermal runaway and helps protect the device from potential damage over extended time. In addition, its molded construction also allows for easy integration with the board, eliminating potential mechanical issues.The NKN2WSJR-73-3R3 is also designed to be resistant to noise spikes, high voltages and currents, and is also designed for high temperature applications. With its superior insulation capabilities, the resistor is protected from electrical shock and is ideal for applications in hazardous environments. This makes it particularly suitable for use in space-constrained environmental applications.Conclusion

The NKN2WSJR-73-3R3 is a high wattage through-hole resistor. With its robust construction and superior insulation capabilities, it is ideally suitable for a range of hazardous environment applications. The resistor is designed to reduce current or voltage passing through a circuit based on Ohm’s Law, while its low thermal resistance helps dissipate heat quickly and reliably. Thanks to its user-friendly construction and frequency range, it is perfect for a variety of current-bearing applications.
