Working Principle

The working principle of the RWR89S4700DRS70 Through Hole Resistor is based largely on its resistor composition. The resistor is made up of a combination of resistor elements that form a resistive bridge to transfer the electrical current from one point to another. This bridge enables the resistor to resist the current, thus providing the desired electrical resistance in the circuit.

The resistor elements are composed of different metals, such as copper, nickel, and alloy resistors. Each of these metal resistor elements has a different resistance, which is determined by the type of metal and the dimensions of the resistor elements. By combining different metals in the resistor bridge, the desired electrical resistance can be achieved. Additionally, the resistor elements can be bonded together with adhesive, soldered, or welded for increased resistance.

In order to provide a reliable electrical connection, the RWR89S4700DRS70 Through Hole Resistor uses two adjustable screws that are heat-treated and electroplated. These screws connect the resistor elements to the circuit, ensuring a strong and reliable connection. Additionally, the resistor is designed with a protective coating that helps to protect it from damage caused by extreme temperatures, dust, moisture, and other conditions.
