RC14KT820R is an axial-leaded through hole resistor that belongs to the family of through hole resistors (THRs). This resistor features a high thermal resistance than other resistors due to its unique construction, and it is ideal for a wide range of applications in industries that depend on reliable power control and current sensing. This article explains the application fields and working principle of RC14KT820R THRs in detail.
RC14KT820R Application Fields
RC14KT820R THRs are typically used in power electronics fields including motor control, battery management, and communication systems. It is widely used in current sensing applications due to its ability to accurately measure current in very low noise environment. The resistor has a low temperature coefficient (< 200ppm/°C) which is essential in high-accuracy current sensing. The low temperature coefficient ensures that the resistance remains constant over a wide range of temperatures and thus provides highly reliable current measurements.RC14KT820R THRs are also used in power transistor and MOSFET control circuits and are popular for use in high power applications. The resistor features a low-temperature coefficient, low power rating, and high dielectric strength, making it ideal for use in power transistor and MOSFET control circuits. The resistor can also be used for amplifier-input matching and temperature compensation circuits and for matching of multiple devices operating at different temperatures.Working Principle of RC14KT820R
RC14KT820R through hole resistor operates on the principle of induced heating which is a process by which current is transferred through a thin conductive element, usually made of copper or silver. As current passes through the element, it generates a thermal effect and heats up, resulting in a change in resistance. The resistor\'s construction consists of a printed circuit board layer and a conductive trace that is coated with a dielectric material, such as ceramic or glass.The current passing through the traces will generate a thermal effect that will cause the trace to heat up, resulting in a change in resistance. The resulting change in resistance will be proportional to the amount of current. The heat generated by the trace will cause the dielectric layer to expand, and this expansion will cause the electrical resistance of the trace to increase. This increase in resistance will be proportional to the amount of current passing through the trace.The resistor has an adjustableresistance range and can be tuned to a specific resistance by the application of a voltage or current. This allows the user to set or change the resistor\'s resistance in order to meet the desired current or voltage value.Conclusion
RC14KT820R is a popular and reliable through hole resistor that is perfect for applications in power electronics. The resistor features high thermal resistance, low temperature coefficient, and low power rating, making it ideal for a wide array of applications. Its construction features a printed circuit board layer and a conductive trace that is coated with a dielectric material, and it operates on the principle of induced heating. The resistor can also be tuned to a specific resistance by the application of a voltage or current, allowing the user to set or change the resistor\'s resistance for precise current or voltage measurements.The specific data is subject to PDF, and the above content is for reference
