Through Hole Resistors - RLR20C1822FRRSL Application Field and Working Principle

Through hole resistors are a type of electrical component that helps in limiting current flow, creating a specific voltage drop or dividing voltage levels in an electrical circuit. In other words, a resistor is an electrical component that can resist the flow of electricity. It can be used for various applications, including voltage divider networks, capacitor discharge protection, current limiting applications, and surge protection. The RLR20C1822FRRSL is such a through hole resistor with a particular application field and working principle.The RLR20C1822FRRSL is a high-power through-hole resistor. It is constructed with the highest grade of wire and ceramic composite material, and is capable of managing power up to 200 watts. Its resistance range is from 0.02 ohm to 2 ohm with an operating temperature range of -55°C to +150°C, making it suitable for military and commercial applications. Its unique design helps this resistor withstand long-term exposure to high temperatures. This through-hole resistor is mainly used in automobile safety applications. It is usually found in the side airbag system, where it controls the pressure of the airbag deployment. Other applications include engine control systems, transmission shift lock, anti-lock brake systems, and other power control systems. It is also used in industrial systems and outdoor lighting systems.The working principle of a through-hole resistor is quite simple. When a voltage is applied across the resistor, a proportional current flows through it. This current is controlled by the amount of resistance in the resistor. Since the resistor has a specific resistance value, the current flowing through it is always determined by that value. As the voltage increases, more current flows through the resistor. This current is further reduced when a greater resistance is applied.The RLR20C1822FRRSL is designed with an external heatsink, which helps to reduce thermal loss. Its internal design ensures that the maximum amount of heat generated within the resistance has been dissipated. This helps to ensure that the resistor does not get too hot and damage any other components in the electrical circuit. Furthermore, its maximum operating temperature of 150°C guarantees that it can handle high power levels for a longer period of time.In conclusion, the RLR20C1822FRRSL through-hole resistor is a vital component in many electrical systems. It is highly durable, reliable, and can handle high power levels. Its resistance range is from 0.02 ohm to 2 ohm, making it suitable for a variety of applications in the automotive, industrial, and outdoor lighting fields. Furthermore, its external heatsink and internal design help to reduce thermal losses and protect other components from damage due to high temperatures.
