Through Hole Resistors are devices, typically cylindrical in shape, consisting of a fixed, unadjustable resistor made of carbon, wirewound, or metal oxide film. Similar to surface mount resistors, Through Hole Resistors come in a variety of shapes and sizes, and with various types of electrical features, such as resistance values, tolerances, and operating temperature ranges. The MFR50SFTE52-300K is one such Through Hole Resistor, used in specific types of applications and having a specific way of working.

The MFR50SFTE52-300K is designed with a 5W power rating, which makes it suited for electronic applications requiring higher wattages than low power resistors. It has a power rating of 300K, which indicates its resistance against electrical flow. The design also ensures an operating voltage of 350V AC and a tolerance of ±5%. This kind of Through Hole Resistor is classified as a "Metal Film Resistor", due to its construction composed of a nickel-iron alloy resistor bar coated with a thin layer of aluminum oxide.

The application field for the MFR50SFTE52-300K primarily involves installations that need higher watt resistors and require reliable performance over prolonged periods. The device is often used in motor controls where continuous and frequent operation is required, as well as in avionic systems that experience long duty cycles.

When it comes to their working principle, most Through Hole Resistors have a resistive element across which the current flow is resisted. In the MFR50SFTE52-300K, this process is made possible by the driving force of the electric current and the geometry of the device. The fixed resistor bar, called the resistive element, is designed with a specific resistance along its length. When an electric current is applied to the resistor, it flows from one end to the other. Along the way, the presence of the resistive element causes the current’s magnitude to decrease, ultimately producing a voltage drop across the resistor. This voltage drop is equal to the product of the resistor\'s resistance and the electric current.

The MFR50SFTE52-300K is a common Through Hole Resistor that is used in engineered systems requiring reliable performance with a higher watt requirement. Its resistive element construction ensures that it resists electrical current flow, producing a voltage drop along its length. With its 5W power rating and 300K resistance value, the device is well-suited for applications necessitating prolonged duty cycles, such as motor controls and avionic systems.
