Through Hole Resistors

Through hole resistors are components used in electronic systems to resist the flow of current, or more specifically, to limit the flow of current. They are one of the most common component types found in electronic circuits, used for an extensive range of applications, ranging from providing bias voltages, current limiting, and signal conditioning, to simple voltage division. These components come in a wide variety of shapes and sizes, but are generally cylindrical in shape, with a hole in the center that is used to mount them into circuit boards and other types of assemblies. One of the most widely used through hole resistors is the CMF5547K000BHBF.

CMF5547K000BHBF Application Field

The CMF5547K000BHBF series from TDK is a range of through hole resistors, designed for use in high power dissipation applications. The resistors feature a two-layer metal element, allowing them to safely dissipate large amounts of energy, while maintaining a low temperature rise. Additionally, they offer low electrical noise with excellent heat resistance and stability. These resistors are ideal for use in power resistors, resistive voltage dividers, current limiting, and other applications where high power dissipation is required. These components can also be used in applications where minimal noise disturbance is desired.

CMF5547K000BHBF Working Principle

The CMF5547K000BHBF series uses a two-layer metal element, with a metal foil layer between two plates of the same material. The two plates are separated by a gap that is filled with a high-resistance material, such as ceramic or epoxy resin.When a current is applied to the resistor, electrons flow through the metal foil from one plate to the other, forming a resistance that limits the current. This resistance is dependent on the size of the gap and the material of the two plates. The greater the gap and the higher the resistivity of the material used for the plates, the higher the resistance of the component. Additionally, the size of the gap may be varied to alter the resistance of the component.

Conclusion

The CMF5547K000BHBF series of through hole resistors from TDK is ideal for high power dissipation applications, and offers outstanding performance in terms of heat resistance and stability. The components offer low electrical noise and can be used in applications where minimal disturbance is desired. They feature a two-layer metal foil element, with a gap between the two plates filled with a high-resistance material that limits the current when a voltage is applied. Thus, this series of through hole resistors provides reliable performance in a wide range of applications.
