Through Hole Resistors and the Application Field & Working Principle of SFR16S0004420FR500

Through hole resistors are components used in electrical and electronics circuits for the purpose of providing a precise amount of resistance for the flow of an electric current. Generally, these resistors are applied in low-voltage circuits, as their ability to dissipate heat is limited. Due to this reason, the majority of through hole resistors are currently utilized in low-voltage electronic systems, such as integrated circuits, cell phones, computers, and other consumer electronic products.

The SFR16S0004420FR500 is a through hole resistor created by Ohmite. It is a capacitive element that is commonly referred to as a “through hole resistor” due to its cylindrical design which allows variables such as distance for lead components to be managed. The SFR16S0004420FR500 has a power rating of 600 W, a resistance value of 40R, and a tolerance of +/- 5%.

The application field of the SFR16S0004420FR500 is in operation in low-voltage, and occasionally mid-voltage circuits. This range of resistor is ideally used for power management in applications such as HVAC systems, telecommunications, and solar energy.

The working principle of the SFR16S0004420FR500 is quite simple. It is a type of resistive element that functions by eliminating a fraction of the total system voltage. This decrease in voltage is done by limiting the current flow through the resistor. Furthermore, the specific type of resistor utilized in this application is an AC rectified oxide resistor. This type of resistor is made of an electrically conductive material such as carbon, and is wrapped with a metal oxide layer which resists the current from flowing through. The resistance value in Ohms is dependent on the resistivity of the material and the length and cross-sectional area of the resistor. As the current passes through, a voltage drop is observed dependent on the current, and the resistor is able to limit the current and keep the voltage consistent.

The SFR16S0004420FR500 component is designed to offer precision in the resistance value and to reduce the variation in the voltage supply. By doing so, precise values can be achieved when voltage or current control is required, avoiding potential system performance reduction that could be caused by power fluctuations or voltage spikes.

In conclusion, through hole resistors, such as the SFR16S0004420FR500, are components commonly utilized in low voltage electrical circuits. They function by providing a precise amount of resistance for the flow of electric current, resulting in a voltage drop. This allows for voltage and current control, as well as providing more precise values which would otherwise be difficult to attain.
