Fixed inductors, sometimes referred to as chokes, are components that store energy in the form of a magnetic field. The CDH80D48NP-221KC is an example of such a component, featuring a power rating of approximately 0.6W and an inductance of 0.033 μH. It is commonly used in a variety of applications ranging from RF signal conditioning to power supply noise suppression.

In order to understand how this fixed inductor works, it is helpful to review some fundamentals of electromagnetism. Basically, if a coil of wire is given a steady current, it will generate a magnetic field. The higher the current, the stronger the magnetic field. The CDH80D48NP-221KC consists of a coil of wire, which is wrapped around a magnetic core. When a current is passed through the coil, the magnetic flux lines created by the current become concentrated in the core, creating a larger magnetic field.

The core of the CDH80D48NP-221KC is made from material with high magnetic permeability, meaning that the flux lines become concentrated to a greater degree. This leads to a greater inductance value, as energy is stored in the form of the magnetic field. When the current through the coil is changed, for example when the frequency of the current is changed, this results in a corresponding change in the magnetic field. This causes a voltage to be induced across the coil, which is proportional to the rate of change of the current.

The CDH80D48NP-221KC is commonly used in RF signal conditioning applications. These devices are designed to block or limit certain frequencies while passing others. By adjusting the frequency of the current through the coil, the impedance of the inductor can be tuned to a specific frequency and the signal can be filtered or blocked as needed. The fixed inductor can also be used in power supply noise suppression. By connecting the inductor in series or parallel with the power supply, the switching noise generated by the power supply can be reduced.

It is also possible to use the CDH80D48NP-221KC in resonant circuits, in order to create a band-pass filter. This is accomplished by using the inductance and capacitance of the circuit to create a resonant frequency. When this frequency is reached, the inductance of the inductor plus the capacitance of the capacitor should equal the resonant frequency of the circuit. This allows the circuit to pass only certain frequencies and block others, thus creating a band-pass filter.

It is evident that the CDH80D48NP-221KC is a versatile component that can be used in a variety of applications. By understanding the fundamental working principle, it is possible to identify the suitable applications for this component and design a circuit that will meet specific requirements. This is a great example of how the principles of electromagnetic fields can be used to solve real-world problems.
