Fixed inductors are electrical components designed to store energy in the form of a magnetic field. These inductors are used to filter or shape the signals in analog circuits and can be used to tune, bias, couples, or provide feedback. One example of a fixed inductor is the CDPH28D11FHF-2R7MC. The following will describe the fields of application and working principle behind this part.

Application Fields

The CDPH28D11FHF-2R7MC is a 2824 Series High Current Power Inductor that features high inductance and low direct current resistance, making this part suitable for use in multiple applications. The power range of the device is 1.2 A max. This inductor is ideal for use in power supplies, backlighting, battery charging, and DC-to-DC converters. Dynamic current handling is up to 33 A.

Designs that use the CDPH28D11FHF-2R7MC can benefit from its small size and excellent high current performance. The inductance of this component is 2.7 uH and its resistance is 0.15 Ohms, making it suitable for use in high frequency applications that require high current capabilities.

Working Principle

The working principle behind the CDPH28D11FHF-2R7MC is the same for all fixed inductors, regardless of size and electrical design. When electrical current passes through the inductor, it generates a magnetic field. When the current is removed, the magnetic field then dissipates, releasing the stored energy. This release of energy is captured as a back EMF, or voltage, which can be used to produce a desired effect. The presence or absence of the back EMF is determined by how quickly the stored magnetic field is released.

This phenomenon can be observed more clearly in a parallel circuit configuration, where two or more inductors are connected in series. In this arrangement, the current flowing through all inductors in the parallel circuit must increase or decrease at the same rate for no back EMF to be generated. This means that the inductors must carry the same amount of current in either direction. By controlling how quickly the current increases and decreases, the designer can determine the strength and frequency of the back EMF.

The CDPH28D11FHF-2R7MC can benefit from its higher inductance and the ability to handle higher currents. The device is designed to operate in both low and high frequency applications, allowing it to control the flow of current to produce more precise results without the risk of overloading or damaging sensitive components.

Conclusion

The CDPH28D11FHF-2R7MC is a highly versatile component that can be used in a variety of applications. Its fixed inductance and low direct current resistance enable it to control the flow of current precisely without the risk of overloading or damaging sensitive components. It is suitable for use in power supplies, backlighting, battery charging, and DC-to-DC converters. Furthermore, the device is designed to operate in both low and high frequency applications, enabling designers to use it as a filter or shape the signals in analog circuits.
