Through Hole Resistors are commonly used to provide electrical safety, reduce signal pulses, and maintain precision when dealing with signals in electronic components. The CMF55118K00FHRE is an example of such a resistor, providing an economical solution for any application. In this article, we\'ll discuss the application fields of the CMF55118K00FHRE and its working principles.

CMF55118K00FHRE Use Cases

The CMF55118K00FHRE is often used in industrial applications as a cost-effective power limiting option. The resistor is designed to manage higher levels of current, making it ideal for use in applications where a higher load capacity is needed. The axial-leaded package also lends itself well to circuit board-level applications where space is a concern. The resistor can also be a good choice for use in audio equipment, where it is used to reduce noise and interference.

The CMF55118K00FHRE is also popular in automotive applications, specifically for electronic control units (ECUs) found in modern vehicles. Here, its high tolerance and accuracy makes it a great option for regulating power. The component can also be used for precision voltage and current control in medical devices such as infusion pumps and respirators.

Working Principle

The CMF55118K00FHRE is an axial resistor with two leads, one pad in the center, and a body. The resistor body is typically made of ceramic, and the two leads are usually made of nickel-plated steel. The resistor contains a metal film inside the body, surrounded by glass. This metal film is the electrical conducting layer. The electrical resistance of the resistor is determined by the ratio between the length and width of the metal film.

The resistor operates by allowing a current to pass through the metal film, which causes some of the electrons to flow through the metal. The resistance of the resistor is determined by the amount of voltage that is applied across the resistor and how much current is allowed to flow through the metal film. The higher the voltage, the more current will flow, and the greater the resistance will be.

In the CMF55118K00FHRE, the resistor has a maximum power rating of 2 watts. This rating signifies the maximum amount of power that can be safely dissipated across the resistor. The resistor must be kept at a temperature no higher than 250°C (482°F), in order to ensure that the device will not be damaged due to an excessive amount of heat.

Conclusion

The CMF55118K00FHRE is an economical and reliable choice for applications that require a high power rating and tight tolerance. Its axial-leaded package is ideal for electronic circuit board-level applications and precision voltage control, and it’s popular in industrial, automotive, and medical applications. The device operates by allowing a current to pass through a metal film, and its resistance is determined by the voltage applied and the current flowing through the metal film.
