Through Hole Resistors are a type of electrical device used to reduce excessive current and direct the flow of electricity in electronic circuits. One of the most common types of Through Hole Resistors is the 20JR20E, which is a fixed metal film resistor. This type of resistor is generally used in electrical equipment and can be used for a wide variety of industrial, commercial, and consumer applications.

The 20JR20E is made up of a strip of metal film, which is formed into a spiral on a standard size cylinder with an epoxy coating. This film is sensitive to temperature and pressure, so it must be handled carefully. The cylinder is then sealed with an epoxy or a thin film of wax to protect it from corrosion and humidity.

It is designed to provide a constant resistance to the flow of electricity, which is necessary for the proper functioning of electronic circuits. This resistor has two leads and is usually found in applications where a low-resistance element is required. It can be used in a variety of situations such as measuring devices, pilot-operated devices, and regulating devices.

The 20JR20E has a wide range of working principles, such as the voltage regulation, the resistor protection and the thermal coefficient of resistance. The voltage regulation is based on the relationship between the voltage applied to the resistor and the output current. This principle is used for controlling the voltage in a circuit, protecting circuits from high voltage levels, and providing a stable and consistent power output. The resistor protection works by limiting excessive current when the voltage applied to the resistor is too high, thus protecting the circuit from damage.

The thermal coefficient of resistance is an important concept when it comes to the 20JR20E. This is the amount of resistance that changes as the temperature of the resistor increases. This is an important factor when considering applications such as LED lights or other high-powered devices. The thermal coefficient of resistance must be taken into account to ensure that the resistor does not overheat and damage the surrounding components.

The 20JR20E is an important device used in a variety of applications. It is used to regulate the voltage in circuits, protect circuits from high voltage levels, and provide a stable and consistent power output. The thermal coefficient of resistance needs to be taken into account when designing circuits with this type of resistor, to ensure that it does not overheat and damage the electronic components.
