Through Hole Resistors – WHA4R0FE Application Field and Working Principle

Through hole resistors, or more accurately known as wire wound resistors, are electrical components that are used to create circuits with a specific resistance value. WHA4R0FE is a special type of through hole resistor that is designed to withstand higher wattage and temperatures than other types of resistors. This makes it a good choice for applications where power is needed but heat dissipation is a concern.The working principle of the WHA4R0FE through hole resistor is similar to that of a standard wire wound resistor. An insulated electrical wire is wound around an iron core using a helical or spiral winding pattern, creating a coil. The resistance value is determined by the number of turns of the wire and the size of the coil. By increasing or decreasing the numbers of turns, or the size of the core, the resistance can be adjusted.When a voltage is applied to the resistor, a current starts to flow through the coil. This current is limited by the resistance of the resistor, and the amount of heat generated by the coil is proportional to the amount of current flowing through it. The higher the current, or the higher the resistance of the coil, the more heat is generated. This heat must be dissipated away from the resistor to avoid any damage.WHA4R0FE through hole resistors are designed to be able to dissipate this heat quickly, making them a good choice for applications where resistance values are high and a lot of power needs to be handled. They are used in many applications such as power supplies, circuit breakers, electronic ballasts, motor controls and other electronic components.In addition to the quick heat dissipation, WHA4R0FE through hole resistors also offer a wide range of other benefits. They are very reliable and long lasting, often outlasting many other types of resistors. They are also available in a wide range of values and packages, making them suitable for a variety of applications.Compared to other types of resistors, the WHA4R0FE through hole resistor is an impressive component. It combines a high resistance value, reliable long lasting design, and quick heat dissipation, making it a good choice for applications where power needs to be handled and heat dissipation is an issue. The cost is also very competitive compared to other resistors.
