Through Hole Resistors

The FMP300FTE73-2K21 is a resistor type that is used in through-hole technology (THT) applications. Through hole technology refers to the use of components that are mounted directly to the PCB (printed-circuit board) using a threaded metal pin, which makes electrical contact with the same component. As a result, they are incredibly robust and durable, making them ideal for applications where reliability and substantially high power ratings are required.

While through-hole resistors offer many advantages over other types of resistors such as surface-mount technology (SMT), they have some drawbacks. For example, their size and complexity make them more expensive and challenging to manufacture. Additionally, because their resistance rating is fixed and can\'t be adjusted, they must be chosen carefully before being used in an application. It is worth noting that, because of their robust construction, large power ratings can be achieved for a relatively low cost.

The FMP300FTE73-2K21 has a wide range of applications. It is commonly used in power supplies, battery chargers, automotive applications, military equipment, and applications involving high vibration. It is also ideal for applications that require power ratings in the kilowatts range (kW). The FMP300FTE73-2K21 is able to handle very high current at high voltages with a resistance tolerance of ±0.1%.

Working Principle

The working principle of the FMP300FTE73-2K21 is straightforward. When a voltage is applied to the two metal pins, the current will pass through the resistor. The amount of current that passes through the resistor will depend on the resistance of the component. The higher resistance of the component, the less current will pass through it.

The resistance of the FMP300FTE73-2K21 can be calculated by using Ohm’s law. Ohm’s law states that the resistance is equal to the voltage that is applied to the resistor divided by the current that passes through it. As the resistance can be set using the variable resistor element, the current can be adjusted as desired. This makes the FMP300FTE73-2K21 one of the most versatile resistors that can be used in a variety of different applications.

Additionally, it is also important to note that the resistance is also temperature sensitive. This means that, as the temperature of the resistor increases, the resistance will decrease. This is because the electrons in the resistor are vibrating more quickly, allowing more current to pass through the resistor at higher temperatures.

The FMP300FTE73-2K21 offers a number of advantages over other types of resistors including its durability, its large power ratings, and its temperature sensitivity. These features make it a popular choice for many applications, from high damping applications to power optimisation in military equipment.
