Through Hole Resistors - CMF55280K00BEEA Application Field and Working Principle

Through hole resistors are an important category of resistors, used for a variety of applications. The CMF55280K00BEEA is an example of a type of through hole resistor. It is a non-inductive, low-profile chip resistor with a wide resistivity range of 0.1 – 130kΩ and a low Noise Figure (NF) of 2DBS.First, the application field of the CMF55280K00BEEA is typically used for high power, high voltage, and high temperature applications. It is well suited for such applications as signal conditioning, power conversion, power distribution, logic and control, and automotive. This resistor has a small size and low profile which allows for excellent placement flexibility and easy integration into tight spaces. It is suitable for military, aerospace, telecommunications, and industrial applications.Next, let’s review the working principle of the CMF55280K00BEEA. This type of through hole resistor is a low power chip resistor which works on the basis of resistive heating. The primary component is a metal film resistor, where the resistor’s ohmic value indicates its resistance. This is because the metal film is deposited onto the resistor chip and the ‘width’ of the film determines the ohmic value. When an alternating current is applied to the metal film, the resistor element will heat up due to being resistive and convert this into internal heat. As a result, this dissipates energy and reduces the current to the desired level.In conclusion, the CMF55280K00BEEA is an example of Non-Inductive, Low-Profile chip resistor from the category of Through Hole Resistors. This resistor has a small size and low profile which makes it suitable for high power, high voltage, and high temperature applications. It works on the basis of resistive heating, where the primary component is a metal film resistor. This metal film is deposited on the resistor chip and it is the ‘width’ of this film which determines the resistor’s ohmic value and its resulting resistance when an alternating current is applied.
