The Through Hole Resistors is an important electronic component used in multiple fields. Today we are going to discuss the RWR81S3R16FRRSL application field and working principle.
RWR81S3R16FRRSL is a type of ceramic body resistor which is used in industrial, telecommunications and automotive applications. It is also commonly used in power supplies, UPS systems and electronics. This resistor is designed with a ceramic body for better dissipation of heat and small size. It has a compact design and is available in a variety of standard sizes. It offers high temperature stability and excellent dielectric strength.
The RWR81S3R16FRRSL has a wide working temperature range between -55℃ and +125℃ and a working voltage rating of 400V. It also offers excellent electrical performance, with a resistance range of 3.3Ω-30Ω. Its insulation resistance is greater than 20MΩ and its dissipation factor is 0.25%.
The working principle of the RWR81S3R16FRRSL is based on the ohmic value of the resistors. The resistor material is made of high-quality ceramics which is mixed with various metal elements. The mixture forms an insulating ceramic film, which is cut into the desired shape. The second conducting layer, usually made of silver and gold, is then applied on the insulating layer.
The current is applied through the two layers and it is resisted due to the ohmic value of the resistor. The electric field passes through the ceramic layer and is opposed by the atoms residing in the metal layer. This causes the current to be opposed and the resistor limits the amount of current that is flowing through the circuit. The metal layer also dissipates the heat generated due to the resistive value.
In summary, the RWR81S3R16FRRSL is a ceramic body resistor suitable for a wide range of industrial, telecommunications and automotive applications. Its working temperature range is -55℃ and +125℃ and its working voltage rating is 400V. It has an ohmic value of 3.3Ω-30Ω, an insulation resistance greater than 20MΩ and a dissipation factor of 0.25%. The working principle of the resistor is based on the ohmic value of the resistor material, with the electric field passing through the insulating ceramic film and being opposed by the metal atoms. This results in the current being limited and also dissipating heat.
