Through Hole Resistors

Through Hole Resistors, also known as axial lead resistors, are one of the most common type of resistors used as fundamental components in electronics today. Resistance components such as the SFR25H0009093FR500 are designed to limit or regulate the flow of electrical current in an electronic system.

Construction

The SFR25H0009093FR500 is a carbon film, axial lead resistor, meaning it consists of a non-conductive core, typically made from ceramic materials such as alumina or aluminum nitride, covered in a conductive material such as carbon film. A thin film of conductive material is applied to the non-conductive core with a sputtering process, a process that applies heat and is similar to that used in the production of vacuum tubes. Axial or "through-hole" resistors have two parallel leads protruding from each end and are typically used in environments where a fixed amount of power or current is dissipated from the resistor.

Use and Purpose

The SFR25H0009093FR500 is a general-purpose resistor that can be used in virtually any application where limited or regulated current flow is desired. The resistors can be used in audio circuitry, as part of a power supply or voltage regulator, or even in logic or digital circuits. They can also be used to reduce the voltage of an electrical signal or to limit the amount of current being passed through a circuit.

Resistance Values

The resistance value of the SFR25H0009093FR500 is typically printed in color codes on the side of the resistor. The resistor\'s resistance value can also be determined by measuring the resistance between the two leads with an ohmmeter. The resistance values of axial resistors typically range from 1 ohm to 1 Mega-ohm. The power rating of an axial resistor is typically also imprinted on the side of the component.

Working Principle

The SFR25H0009093FR500 works in an ohmic manner in which current is directly proportional to voltage across its leads. When electricity is applied to the component, the electrons attempt to traverse the material of the resistive body, and this resistance causes the electrons to lose energy. This process creates heat energy, which is then dissipated from the component\'s leads.

Conclusion

The SFR25H0009093FR500 is a Through Hole Resistor that is extremely useful in countless applications. With its wide range of resistance values and power ratings, it is an ideal choice for any circuit design. It is a cost-effective, robust, and reliable component that has a multitude of uses.
