Introduction of Through Hole Resistors

Through hole resistors are commonly used components in electrical and electronic equipment. These components are used to limit the amount of current passing through a circuit. A resistor is a passive element that resists the flow of current and also dissipates energy in the form of heat. The resistance of a resistor is generally expressed in ohms.

Types of Through Hole Resistors

Through hole resistors can be divided into two main categories, namely, fixed resistors and variable resistors. Fixed resistors are resistors with a predetermined value, which cannot be changed or adjusted. On the other hand, variable resistors, also known as potentiometers, are resistors whose resistance can be varied according to the application. They are often used in applications in which an adjustable resistance is required.

SFR25H0002553FR500 Application Field and Working Principle

The SFR25H0002553FR500 is a through hole resistor with a resistance of 25.5k ohms. This resistor belongs to thefixed resistor category. It is constructed with a carbon-film and metal-oxide resistance elements on top of a ceramic, non-flammable body. The SFR25H0002553FR500 works on the principle of resistive heating. When current passes through the resistor, the resistor produces heat as a result of electrons colliding with the atoms in the material of the resistor. The amount of heat generated is directly proportional to the amount of current flowing through the resistor, and the amount of resistance of the resistor. Therefore, the SFR25H0002553FR500 can be used to regulate the current through a circuit.The SFR25H0002553FR500 is generally used in applications that require high-power handling. The resistor is designed to dissipate 2 watts of power, and can withstand a voltage of up to 250V. This makes it suitable for applications such as power supplies and voltage regulators.

Conclusion

Through hole resistors are essential components in any electronic system. The SFR25H0002553FR500 is an example of a through hole resistor with a resistance of 25.5k ohms. It is a fixed resistor that is mainly used in applications that require high-power handling. The resistor works on the principle of resistive heating and is capable of dissipating 2 watts of power.
