RWR80S1R21FSS73

Through Hole Resistors are passive components that are used to control the amount of current flowing through a circuit. They are designed to provide a uniform resistance in a circuit, to limit current, to divide voltage, and to protect other components from over-current or voltage overloads. The RWR80S1R21FSS73 is a Through Hole Resistor that has its own unique application fields and working principles.

The RWR80S1R21FSS73 is commonly used in areas where high frequency ripple noise is expected, such as AC/DC converter circuit and audio signal processing. It has good frequency characteristics and is designed for high stability under temperature cycling conditions. This type of resistor has an operating temperature range of -55°C to +125°C, and a power rating of up to 1/4 Watt. With its low temperature coefficient, excellent frequency characteristics, and good high level overload features, this type of resistor is used in many application areas.

As far as the working principle is concerned, the RWR80S1R21FSS73 is basically a variable resistor. Its value depends on the applied current, and the internal resistor is adjusted by adjusting the voltage applied to it. A voltage is applied to the resistor, which creates an electrical field around the resistor. As the current flowing through the resistor increases, the electrical field increases, resulting in a decrease in the resistance of the resistor. This process is also known as Ohm\'s law.

The RWR80S1R21FSS73 is also used as a voltage divider for the same reason. When a current is injected into the resistor, the voltage across the resistor will be divided according to the ratio of the two resistors connected in parallel. The sum of the voltages on the two resistors is equal to the total voltage applied. This property of the Through Hole Resistor makes it very useful in the design of analog circuits for power electronics and other varied applications.

Overall, the RWR80S1R21FSS73 is a Through Hole Resistor that is used in many applications due to its high frequency ripple noise characteristics, excellent frequency characteristics, and good over-current or overload features. Its operating temperature range is from -55°C to +125°C, and its power rating is up to 1/4 Watt. Its working principle is based on Ohm’s law, which states that the current flowing through a resistor changes the resistance of the resistor according to a predetermined ratio. Lastly, it is also used as a voltage divider, which can be used in different analog circuits.
