Through Hole Resistors

Through hole resistors, also known as hole or mounting through, are electrical components that serve to oppose current flow in a circuit. They come in a variety of sizes and ratings, making them a useful and versatile component in a wide variety of electronic applications. As resistors, their main purpose is to decrease current going through a circuit when activated.This can be used to help create more complicated circuits for more specific functions.

SFR2500004642FR500 Application Field and Working Principle

The SFR2500004642FR500 through hole resistor is a high power resistor used in many commercial and industrial applications. This resistor has long-term stability and is designed to run at elevated temperatures. It is ideal for applications where extremely high power, long-term performance and high temperature operation is required. It is particularly suitable for industries such as automotive, power supplies, and telecommunications.

The working principle of a through hole resistor is based on the Ohm\'s Law. This law states that the current passing through a resistor is directly proportional to the voltage applied to it. This means that as the voltage increases, the current passing through a resistor will also increase. In a through hole resistor, this current is limited by the size of the resistor and the resistance of the material it is made from. When a certain current is passed through the resistor, it creates a certain voltage drop, which must be equal to the applied voltage, since the resistance will remain constant.

The SFR2500004642FR500 through hole resistor is a high power resistor with a resistance of 250000 ohms, meaning it can handle a large amount of current without overload.
