Through hole resistors are essential components in electronics and electric circuits. They are generally categorised according to their nominal resistance value and physical form. One type of through hole resistor, the RWR80S38R3FSS73, has a power rating of 0.3 W and 0.8 Ω at 25°C.

The RWR80S38R3FSS73 is a four-terminal resistor, meaning that it has two outer terminals and two inner (or midsection) terminals. The two outer terminals are used for connections to other components, while the inner terminals are used to adjust the resistor\'s resistance. The inner terminals are wider than the outer terminals, making it easy to adjust the resistor without shorting it out.

This type of resistor is used in low-power, high-accuracy applications such as signal conditioning circuits and temperature sensors. In these kinds of circuits, the RWR80S38R3FSS73 is arranged in a "bridge" configuration, with one resistor in the top left corner and another in the bottom right corner. The two resistors are interconnected through the inner terminals, creating a balanced bridge circuit. This type of arrangement allows for fine adjustments to the signal being passed through the circuit, and makes it easy to maintain a stable voltage or current.

The working principle of the RWR80S38R3FSS73 is based on the basic Ohm\'s law. This law states that electric current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R). In other words, an increase in voltage will cause a current to flow, and an increase in resistance will decrease current flow. By properly adjusting the resistance with the inner terminals, the current can be manipulated to get the desired effect.

In summary, the RWR80S38R3FSS73 is a four-terminal resistor with a power rating of 0.3 W and nominal value of 0.8 Ω at 25°C. It is used in low-power, high-accuracy applications and operates on the principle of Ohm\'s law. With its four terminals and balanced bridge configuration, it can be easily adjusted to get the desired current flow.
