Through hole resistors are an essential electronic component used for applications such as impedance matching, filtering, power dissipation, timing, and signal conditioning. SR20-0.020-1%, a specific type of through hole resistors, are widely used due to their high reliability, small size, low power consumption, and low cost. SR20-0.020-1% resistors are made of printed carbon film and a metal alloy wire that is wound into a cylindrical core and fixed onto a base. The base is constructed from either an epoxy composite, hard plastic, or ceramic. The resistance value of the resistor is indicated by a color code that is printed onto the resistor body. The color code varies from manufacturer to manufacturer, but the standard international color code consists of four color bands. The first two bands indicate the first two digits of the resistance value; the third band denotes the number of zeros to add to the numerical value; and the fourth band indicates the accuracy of the resistor. Generally, SR20-0.020-1% resistors are used for moderate power applications such as signal conditioning, voltage regulation, and temperature measurement. They are also used for low-power applications such as AC/DC current flow control, current sensing, and voltage dividers. Additionally, they are used in many audio and radio frequency circuits. SR20-0.020-1% resistors are manufactured in an axial orientation, meaning they have two leads extending out from both sides of the cylindrical core. This allows for easy installation in a variety of electronic circuits. Additionally, the leads of the resistor are dipped in a protective coating which prevents the leads from corrosion and oxidation. The working principle of SR20-0.020-1% resistors revolves around Ohm\'s law. Ohm\'s law states that the current through a conductor between two points is directly proportional to the voltage across the two points. In other words, the voltage and current are inversely proportional to the resistance. This means that when the voltage increases, the current decreases, and when the voltage decreases, the current increases. SR20-0.020-1% resistors work by providing a specific level of resistance to the flow of alternating or direct current. This allows them to tame and regulate the level of current in a circuit. In summary, SR20-0.020-1% resistors are a type of through hole resistors that are widely used for various applications such as power dissipation, signal conditioning, and voltage regulation. They are made from a cylindrical core, a printed carbon film, and a metal alloy wire. Their working principle revolves around Ohm\'s law, which states that the current through a conductor between two points is directly proportional to the voltage across two points. Even though these resistors have simple operation, they are essential components in any electronic circuits.
