Through Hole Resistors are electronic components used in circuits to control or limit the flow of current. The 85FR402 is one type of resistor designed for applications where high power dissipation is required. It is a Through Hole Resistor with a low thermal resistance, allowing more power dissipation than many other types.

The 85FR402 is constructed of two wire leads that extend through an insulated enclosure with a heat sink and the resistor body. The resistor body is made of metal alloy and the heat sink is made from aluminium. The two leads are connected to each other, forming the resistor. The insulated enclosure provides protection for the resistor body and heat sink, preventing heat transfer or short circuits in the circuit.

The 85FR402\'s power dissipation is based on its composition and the amount of current that flows through it. The alloy used in its construction is designed to dissipate heat at a specified power, and the size and shape of the resistor body can also affect its dissipation. For example, a longer or bigger resistor body will dissipate more power than a shorter or narrower one. The larger size also allows more current to pass through the resistor, thus increasing the power dissipation.

The working principle of the 85FR402 is based on Ohm\'s Law. This law states that the current through a resistor is proportional to the voltage across it, and the resistance is equal to the voltage divided by the current. In the case of the 85FR402, the resistance depends on the material used in its construction, which is determined by its power dissipation. When a current flows through the resistor, it generates heat, the heat is then dissipated through the heat sink and into the surrounding environment.

The 85FR402 is a versatile component that is commonly used in a variety of applications. It can be used in power supplies, amplifiers, motors, and other components that require high power dissipation. It is also often used in circuits that require temperature stabilization, such as in the automotive industry. Its ability to dissipate power and withstand heat makes it a reliable and durable component.

The 85FR402 is a Through Hole Resistor with a low thermal resistance and high power dissipation, making it an ideal component for applications that require rapid heat dissipation. Its construction and working principle are based on Ohm\'s Law, allowing it to dissipate power and resist heat buildup in a wide range of applications. Because of its reliability, durability, and usefulness, the 85FR402 is a popular component used in many applications.
