Through Hole Resistors

Through hole resistors are fixed value components that are used in a wide variety of modern circuit designs. They are essentially resistors with a defined resistance value that is physically marked on the part\'s body. CMF654M0000FKBF is one of the most commonly used through hole resistors, and it is often used as a replacement for more expensive standard resistors. The ability to quickly identify its resistance value makes it ideal for quick repair and revision of existing circuit boards.

Application Field

The CMF654M0000FKBF through hole resistor is used in a variety of applications, from electronic testing to home audio and television systems. Its small size and low cost make it a popular choice for applications where space is limited or budget is an issue. It is also utilized in computers and communication devices, as well as energy-saving devices.

The CMF654M0000FKBF is typically used as part of a circuit board, either on the surface or mounted behind a shield. It is also frequently used as part of a PTC (Positive Temperature Coefficient) resistor assembly, a combination of several components that can be used to limit current or voltage in a circuit. Additionally, various transformer types use CMF654M0000FKBF resistors as part of their primary or secondary coils.

Working Principle

The working principle of the CMF654M0000FKBF through hole resistor relies on the tendency of electrical current to oppose any changes in electrical potential. When a current passes through a resistor, some of the electrical energy is lost as heat, and the resistor is said to be dissipating power. The CMF654M0000FKBF has a resistive value that is defined by its construction. This resistance is what limits the current through the resistor, limiting the potential voltage or power levels.

The voltage across the resistor is determined by Ohm\'s Law, which dictates that the voltage drop across a resistor is equal to the product of the resistor\'s resistive value and the amount of current passing through it. The power dissipated by the resistor can be calculated using the formula P = I² x R, where I is the current and R is the resistance value. This formula is used to determine the amount of heat generated by the resistor.

The CMF654M0000FKBF is designed to exhibit a predictable linear resistance-temperature relationship, meaning that its resistance will remain relatively stable across a wide temperature range. This not only allows for a predictable voltage or current rating, but also makes it suitable for precise current-sensing applications.

Conclusion

In summary, the CMF654M0000FKBF through hole resistor is a highly effective component that is used in many applications due to its small size and low cost. It is used to limit current or voltage in a circuit and is often part of a PTC resistor assembly. Additionally, its predictable linear resistance-temperature relationship makes it suitable for current-sensing applications. While there are more accurate resistors out there, the CMF654M0000FKBF is an impressive choice when budget and space are considerations.
