The RER45F1820RCSL is a chassis mount resistor that is used in a variety of applications. It is a highly reliable and economical range of resistor products manufactured in the United States. This particular device has an absolute tolerance of 5% and is rated for up to 1000 volts. It is also UL 94 V-2 compliant and RoHS compliant.Chassis mount resistors are used in a variety of applications, from automotive to commercial to military. By their basic nature, they are designed to provide electrical resistance. The resistance can be set to a nominal value, or, depending on the application, may be variable. The RER45F1820RCSL is a fixed resistor, meaning the resistance between its two leads is predetermined, and as such can not be adjusted.The most common application of the RER45F1820RCSL is as a power resistor. It is designed to handle current up to 600 Amps. It is also applicable as a voltage divider, allowing the application of a certain voltage to be divided among multiple outputs. Furthermore, the RER45F1820RCSL can be used to reduce the power dissipated from active components like transistors and diodes.The working principle of the RER45F1820RCSL is simply the flow of electrons through the resistor. The resistance of the resistor is determined by its physical characteristics - its size, shape, and material. When a current is applied across the resistor, the electrical energy is dissipated in the form of heat. This heat loss is proportional to the voltage applied and the resistance of the resistor, and is known as power dissipation.The RER45F1820RCSL has a power rating of 10 watts. As such, it is ideal for applications that require efficient heat dissipation. The heat that is dissipated can be controlled through the use of a heatsink, or a cooling fan, depending on the application.In summary, the RER45F1820RCSL is a chassis mount resistor used primarily for power resistance applications. It has an absolute tolerance of 5%, is rated for up to 1000 volts, and is UL 94 V-2 complaint. Its working principle is based on the flow of electrons through it, and, when properly cooled, can dissipate 10 watts of power without damage. This type of resistor is an integral component in many commercial and military applications, and should be selected with care.
