The NKN200JR-73-0R68 is categorized as a Through Hole Resistor. This type of resistors have several applications and a few specific working principles associated to them, which will be covered in the following text. Applications: Through Hole Resistors are used to reduce the current, divide potential, drain excess voltage, filter signals, aid in circuit stabilization and even out frequency responses. They can even be used to aid in damping transient voltages spikes and power inrush protection. One particular application which makes use of the NKN200JR-73-0R68 is as part of power supplies and power converters, specifically to protect against short circuit and over-load conditions. Working Principles: Through Hole Resistors typically take the form of a resistive cable, metalizations, films or foils, these are then fitted onto a ceramic, glass or metal substrate, in the case of the NKN200JR-73-0R68 it is a ceramic substrate. When current is passed through a resistive component such as these, voltage is dropped, the amount of voltage dropped depends on the type of material and its resistive rating. These are affected by several factors, those being the type of material (in this case the ceramic), its length and width, and the material used in the substrate and its resistive rating. At the same time, these resistors also heat up when current is passed through them, this heat is generated according to Joule’s Law, which states: “The amount of heat produced by a resistor is proportional to the square of the current passing through it.” The resistive rating of the NKN200JR-73-0R68 causes the heat generated to be dissipated at an acceptable level. The resistors will heat up faster with higher amounts of current, which can cause the device to overheat. To prevent this, the resistor is designed to be thermally insulated so that the heat will not be conducted into the adjacent parts of the circuit, thereby allowing it to dissipate the heat more efficiently.In addition to these, Through Hole Resistors also typically feature capacitance and inductance properties which can act to filter signals in various ways. This can be achieved by adding a low or high pass filter to the component, or by using a band pass filter, the particular type used will depend on the circuit’s requirements.In summary, the NKN200JR-73-0R68 is categorized as a Through Hole Resistor and has both applications and working principles associated with it. Its applications range from power supplies and converters, to damping transient voltages spikes, and power inrush protection. It is also used in filters by adding a low or high pass filter to the component, or by using a band pass filter. As for its working principles, it works by using the material’s resistive rating to reduce the current and drop the voltages, with heat generated by the current following Joule’s Law and being dissipated by the components thermal insulation.
