Through Hole Resistors: RN55D4704FR36 Application Field and Working Principle

Through hole resistors are widely used in various electronic circuitry, especially when circuit designers need to handle power or require a precise value of resistance. Common through hole resistors are usually used to provide power for a wide range of applications from low- to high-power. Nevertheless, some special types of through hole resistors are used for special purposes and are equipped with unique features to meet these requirements. In this article, we are going to take a look at the application field and working principle of a specific type of through hole resistor - the RN55D4704FR36. The RN55D4704FR36 is a through hole resistor from the Metal Oxide Film resistor series by Panasonic. It is a 4-terminal radial style resistor and has the power-handling capability of 4 watts. Its two isolated metal layers provide insulation against the external environment for any power applications. Furthermore, it is equipped with a power rating of 0.5% tolerance, making it highly reliable and precise for most applications. The most common application of the RN55D4704FR36 is as a power resistor. It is most suitable for applications that require high power ratings, such as in power supplies or when providing protection against surges and other safety components. Its internal resistance is perfect at isolating any power surge and provides the necessary protection to the circuit. It is also suitable for providing power for LED lighting, heaters, and motor-based applications. The working principle of the RN55D4704FR36 is based on its design as an electrically-isolated through hole resistor. It has two layers of metal material separated by an oxide layer, which provides insulation between the two layers and also acts to reduce the electrical contact between the two. As the voltage is applied, a current flow will be created which passes through both metal layers, thereby creating a resistance that is determined by the parameters of the oxide layer in between. The RN55D4704FR36 also has the capability of dissipating waste heat energy that is generated by its components. As the resistor’s internal temperature increases, its components will start to expand, leading to more contact between the two metal layers, which in turn leads to more energy being dissipated. The resistor is thus designed to able to be heat-resistant up to a certain temperature to ensure its efficient operation. In conclusion, the RN55D4704FR36 is a through hole resistor with power-handling capabilities of up to 4 watts and a tolerance of 0.5%, making it ideal for applications that require reliable and precise power supplies. Its internal resistance and oxide layer provide insulation and efficient dissipating of heat energy, making it highly suitable for power and heater-based applications.
