The CMF552R2000FKEB is a Through Hole Resistor which is widely used in various applications. It is a high precision, adjustable resistor with a higher withstand voltage and power rating than other components. It features a low ohmic range, low temperature coefficient, low inductance and a broad range of resistance values. It is applicable to a wide range of applications, including audio, communication, medical, automotive, portable devices and digital circuits.

The CMF552R2000FKEB is a two-terminal resistor, with a resistance range of 0 to 2000 ohms. The resistance value can be changed by adjusting either of its two terminals. The terminals are connected to each other through a thin metallic film. This film has a special coating to prevent oxidation and has an adjustable resistance through which a variable current can be passed.

A wide range of application fields can benefit from the CMF552R2000FKEB, including automotive, communications, audio systems, medical and digital equipment. In automotive, they are used for regulating the voltage supply to the electronic control unit. In communications, they can be used for setting transmission and reception thresholds. In audio systems, the resistance value can be used to optimize the audio system’s frequency response. In medical applications, the low heat generation and low impedance make the CMF552R2000FKEB an ideal choice for medical instrumentation applications where precise current is required.

The working principle of the CMF552R2000FKEB is based on a phenomenon called "electrostatic field emission". This phenomenon occurs when a high-voltage current passes through the resistor. The current induces a charge on the thin metallic film, which generates an electric field. This electric field exerts a force on the metal which in turn causes it to contract or expand depending on the direction of the current. The expansion or contraction of the film is what allows the resistor to change its resistance value.

In addition to its working principle, the CMF552R2000FKEB also relies on a special coating to protect the resistor from oxidation. The coating helps to ensure a longer operating life and greater stability in harsh environments. The resistor also features a built-in strain relief collar that helps protect the metal film against mechanical stress.

Overall, the CMF552R2000FKEB is a high precision adjustable resistor, ideal for a wide range of applications. It is capable of withstanding high voltages and temperatures while maintaining a high level of accuracy. The built-in protection features help it to last longer, and its resistance range allows for a wide range of applications. It is an indispensable component in automotive, communications, audio systems, medical and digital equipment applications.
