Through Hole Resistors – OF393JE application field and working principle

Through hole resistors play an important role in a wide range of fields, from electronic components, to medical devices and even aerospace engineering. The OF393JE resistor is a major product in this family of devices, designed for high-power demanding applications with minimal temperature coefficient and significant reliability. This article will discuss the application field and working principles of OF393JE.The OF393JE through hole resistors are designed for high voltage applications up to 500V, high power dissipation of up to 500 W, and low temperature coefficient, meaning they can be used in extreme environments, both hot and cold. This makes them well-suited for applications that include industrial as well as aerospace and defense systems. For example, they can be used for high voltage insulation, voltage balancing, current limiting, and spark suppression in embedded systems, medical devices, and even aerospace control systems.The basic working principle of the OF393JE through hole resistor is simple – it converts electrical energy into heat energy. It does so by creating a resistance to the flow of electrons, making them spend more time inside the device. As they move through the resistor, they experience collisions with the atoms of the material, and as a result, some of their energy is converted to thermal energy, thus increasing the temperature of the resistor.The OF393JE resistor has a number of features that make it a superior choice for high voltage, high power applications. First, its metallic foils are insulated by an insulating medium, protecting the device from environmental influences and dissipating heat. Second, its heat sink allows the resistor to conduct heat away and prevents it from overheating. Third, the resistor has a built-in thermistor which helps to control the temperature of the resistor and ensures that it does not exceed the specified operating temperature.The main advantage of using the OF393JE through hole resistor, apart from its many features, is that it can offer a significant reduction in manufacturing cost. This is because it requires fewer components than other types of resistors, such as chip resistors and surface mount resistors. In addition, the device can be quickly connected to a circuit and offers flexibility in terms of size and mounting.The OF393JE resistor is a versatile device that is suitable for a wide range of applications. Its high voltage, high power, and low temperature coefficient capabilities make it well-suited for use in extreme environments, and its inherent design features allow for a considerable reduction in manufacturing cost. Features such as a heat sink, thermal protection, and insulation provide added flexibility, robustness, and reliability. The OF393JE resistor is a highly efficient and reliable device that can offer significant cost savings in applications ranging from embedded systems to aerospace engineering.
