Through Hole Resistors: CMF5590K000BEBF application field and working principle

Through hole resistors are electrical components that are made to resist the current flowing through them. They are used in many different applications and can be found in a variety of configurations depending on the specific use-case. The CMF5590K000BEBF is a specific type of through hole resistor manufactured by the company Valpey-Fischer. This resistor type is commonly used in a wide range of applications including power systems, audio/visual equipment, telecommunications, automotive electronics, and even medical equipment.

Construction and Working Principle

The CMF5590K000BEBF resistors are comprised of a double sided, terminated metal or ceramic substrate with multiple, concentric conducting rings on the surface of the substrate. The concentric circles are usually color coded to indicate the resistance value. On the center of each ring a polarity mark is printed to identify the positive or negative connection when wiring the resistor. This type of through hole resistor is typically used in high-voltage applications where a high power rating is required. The resistor works by harnessing the energy of the current flowing through it and transforming it into thermal energy. This thermal energy is dissipated through the substrate as heat energy, thereby limiting the current that is able to pass through the resistor. The resistance value of the resistor is defined by the distance between the terminal points of the rings on the surface of the substrate. The shorter the distance, the lower the resistance value.

Applications

As mentioned, the CMF5590K000BEBF resistor is mainly used in high-voltage, high-power applications. It is often employed in automotive electronic systems, power systems, and audio/visual equipment as a means to limit the current flowing through these systems. In telecommunications, this through hole resistor is used to reduce power losses and provide additional safeguards from power surges. The typicral application range of this resistor is from 1kV to 4kV. In addition, this type of resistor is employed in medical equipment such as X-ray machines, power sources, and tube coils. This is due to its high-voltage and high-power rating, allowing it to withstand the vibrations and power spikes that are associated with medical equipment. By providing a current limiting element, the resistor helps provide additional protection for both the equipment and the operator.

Conclusion

The CMF5590K000BEBF through hole resistor is a versatile resistor that has many applications ranging from automotive electronics to medical equipment. Its construction is comprised of concentric conducting rings on a double sided, terminated metal or ceramic substrate. The size of the rings determines the resistance value, and the polarity mark on the center of each ring identifies the positive or negative connection when wiring the resistor. This type of resistor helps limit the current and provide protection for high-voltage, high-power systems.
