Through Hole Resistors
Through hole resistors are components used to restrict the flow of current in an electrical circuit. They are a fundamental piece of any circuit board and are used to control the amount of voltage passing through the board. The RWR81S40R0FRBSL is a type of through hole resistor. In this article, we will discuss the application field and working principle of this particular resistor.
Application Field
RWR81S40R0FRBSL through hole resistors are designed to offer high output power and current carrying capabilities. They are an excellent choice for applications where high power and/or high current is required, such as power supply circuits, automotive electronic circuits, boiler control systems, and other high-end applications. This type of resistor has a wide operating temperature range, up to 125°C, making it suitable for a variety of industrial applications.
Working Principle
RWR81S40R0FRBSL through hole resistors work on the principle of resistance. When voltage is applied across the ends of the resistor, it will heat up as the electrons pass through. This heat causes resistance, and the level of resistance will depend on the resistor material and the size of the resistor. The higher the resistance, the less current will be allowed to pass through. This is the basic principle at work in all resistors.
Conclusion
RWR81S40R0FRBSL through hole resistors are substantially different from surface mount resistors. They are designed to handle more power and current and are suitable for a wide range of high power applications. The basic working principle of any resistor is the same, the higher the resistance, the lower the current will be allowed to pass through. These electrical components are a vital part of any circuit board and are commonly used to control voltage levels and ensure the smooth operation of the device.
