Through Hole Resistors: RWR81S3920FSS70 Application Field and Working PrincipleThrough hole resistors are commonly used components in electronics. They are available in different sizes and designs, and all share a basic structure of a cylindrical body with two metal prongs sticking out of one end. The size of the resistor affects the amount of resistance it imparts on the circuit, as well as the power it can handle. Among these resistors, the RWR81S3920FSS70 has been particularly notable in its ability to perform exceptionally in various applications. In this article, we’ll be discussing its application field and working principle.Application FieldRWR81S3920FSS70 is applicable mainly in the field of industrial electronics. It is designed to resist high levels of electrical shock and/or vibration while having very low levels of power loss or drift. This makes it an advantageous choice for applications with long operating periods or high ambient temperatures. It is especially suitable for applications in missions requiring high reliability and low maintenance. In addition, RWR81S3920FSS70 has a wide power range suitable for use in both consumer and industrial electronic devices. This allows for continuous supply of power to resistors, allowing for higher efficiency and better performance in applications that require high currents and precise voltage regulation. Its wide power range has also resulted in the increased use of the resistor in motor and solenoid control circuits. Working Principle RWR81S3920FSS70 is able to function by controlling the current in a circuit according to Ohm’s Law. Ohm’s Law states that the voltage drop across a resistor is equal to the resistance multiplied by the current passing through the resistor. Therefore, when a current passes through RWR81S3920FSS70, the resistor will drop the voltage accordingly depending on the size and number of resistors. This voltage drop is measured in watts and is used to determine the power rating of the resistor. The greater the power rating, the larger the resistor can control current. In addition, its tolerance helps to reduce the difference between the resistance values and the actual measured values, providing tighter and more precise control over the circuit.RWR81S3920FSS70 integrates three power elements into one: resistance, stability and power control. Its stability often surpasses other resistors, and its high power control ensures reliable operation of the circuit without any sudden changes to the power levels. As such, it proves to be a powerful and reliable resistor for industrial applications. In summary, RWR81S3920FSS70 is an exceptionally reliable resistor for applications requiring stability, high power control and resistance to extreme environments. Its versatile application field covers consumer and industrial electronic devices, sometimes requiring long periods of operation or high temperatures in order to perform optimally. Its working principle is based on Ohm’s Law, and its power elements including resistance, stability and power control provide precise and reliable operation of the circuit.
