Through hole resistors are widely used in various electronic applications. They are designed to provide resistance to current flow and increase resistance to voltage. The resistance of these through hole resistors is usually determined by the material used as the base material or the layer on the resistor body. In certain application fields, the resistance is specified by the manufacturer. The RWR81S21R5FMRSL is a type of through hole resistor that falls into the category of resistive elements. It is typically used in high power applications, as it has a high power rating for its size.
The RWR81S21R5FMRSL through hole resistor has a power rating of 200W and a resistance range of 5 Ohms to 500K Ohms. It is constructed of a metal oxide film coated with a ceramic insulation material that is then encased in an epoxy resin. The resistance of the resistor is adjusted by heating and cooling the resistor body and changing the resistance structure within it. The resistor is then moisture-sealed in an epoxy resin to add further protection against electrical hazards.
The RWR81S21R5FMRSL through hole resistor is generally used in high power applications as well as signal processing and filtering circuits. Because of its high wattage rating, it is also used in power supplies, switching circuits, and other circuits where a high power rating is necessary. The RWR81S21R5FMRSL is also used in AC and DC circuit applications where it is necessary to adjust the resistance in an application.
The working principle of the RWR81S21R5FMRSL resistor is based on its resistance structure. When a current passes through the resistor, the resistor absorbs the energy in the form of electrons. This is known as the Joule heating effect. This heating then causes a change in the resistance value of the resistor, allowing it to provide varying amounts of resistance in a circuit.
The RWR81S21R5FMRSL through hole resistor is popular for its high power rating, large resistance range, and high temperature tolerance. Its ability to adjust resistance values in an application makes it the perfect component for use in high power applications and signal processing and filtering circuits. Its construction and materials also make it one of the most durable types of resistors on the market.
