Through hole resistors are a type of resistor that are used to build and control electrical circuits. The RNC60H1431FSB14 is an example of a through hole resistor with high precision and selectivity. An understanding of its application field and working principle can help you choose the most suitable resistor for your circuit design.

Application Field

The RNC60H1431FSB14 through hole resistor is most commonly found in amplifiers and audio components. This is due to its low noise levels and high precision resistance values (0.2% tolerance). It is a 0.2 ohm resistor with a maximum power dissipation of 1/2W, and also features a high dielectric strength, making it suitable for measuring and buffering sensitive electrical signals. It is a reliable part that can be used to ensure that the signal remains within the desired range, and can endure long-term use even in harsh environments.

Working Principle

The RNC60H1431FSB14 through hole resistor uses a carbon-film element to control the resistance value of the component. When electricity passes through the element, the heat energy generated causes a low resistance across the film. This enables the current to flow. The resistance is determined by the number of turns in the resistor winding and the diameter of the carbon-film element. To adjust the resistance, the turns are increased or decreased, or a thicker or thinner element is used.

The resistor also features a protective coating that prevents oxidation of the carbon-film element. This coating is necessary to ensure that the resistance remains stable over the lifetime of the resistor. Additionally, the coating helps avoid hazards such as arcing or shorts caused by oxidation.

To ensure the correct resistance value is achieved, the heater current must be set to the desired value. This is done by adjusting the current to the appropriate range and then measuring the voltage across the resistor. The resistor must then be adjusted according to the measured voltage.

The above describes the application field and working principle of the RNC60H1431FSB14 through hole resistor. Understanding these concepts can help you choose the most suitable resistor for your circuit design. Through hole resistors offer many advantages, such as low noise and high precision resistance values, that can make them an ideal choice for amplifiers and audio components.
