Through Hole Resistors

SFR2500002943FR500 application field and working principle

Through hole resistors are one of the most widely used types of resistors in the electronic industry. They are usually cylindrical or rectangular resistors with one or two metal plates at either end connected by a solid core, often made from carbon or metal oxide. The metal plates can be made from either aluminum, copper, or gold, depending on the application. Through hole resistors are most commonly used for circuit board layout, current sensing, and temperature measurement, as well as voltage sensing, current limiting, and power regulation.

The application area of the SFR2500002943FR500 through hole resistor is primarily suited for low voltage, high accuracy applications. It can be used to measure current up to 250 mA AC/DC, and can be used with temperatures ranging from -20 to +85°C. It is also capable of insulation withstand voltages up to 50V AC/DC, making it a good choice for industrial, automotive and medical applications.

The working principle of the SFR2500002943FR500 through hole resistor is fairly simple. The resistor is made up of two plates connected by a solid core. When electricity or current travels through the resistor, some of it is converted into heat by the metal plates, reducing the current to the desired value. The amount of current that is reduced by the resistor is directly proportional to the amount of resistance, which can be adjusted by increasing or decreasing the size of the plates.

The SFR2500002943FR500 through hole resistor is an effective and reliable component for many industrial, automotive, and medical applications. Its low voltage, high accuracy, and insulation resistance make it an excellent choice for many electronic designs. The simple working principle of the through hole resistor means that it is easy to use and maintain, and provides accurate voltage and current regulation.
