Fixed inductors are passive components that store electrical energy in a magnetic field. Specifically, they are composed of a coil of wire wrapped around a core material. This core material consists of a magnetic material such as iron, steel, or ferrite. The magnetic field is created when a current flows through the wire coil.

The PD43R-123M fixed inductors can be used in a wide range of applications, including power supplies, DC-DC converters, voltage converters, radio frequency (RF) choke filters, and high-frequency resonators. They are commonly used in smartphones, tablets, and audio systems.

PD43R-123M Application Field

The PD43R-123M fixed inductor can be used in a variety of applications, depending on the design specifics of the inductor. For example, it can be used as a voltage doubler, which generates an output voltage that is twice the supply voltage. It can also act as a voltage regulator, providing additional smoothing and regulation to a DC voltage.

Working Principle

The working principle of a PD43R-123M fixed inductor is quite simple. When a current is applied to the inductor, the magnetic field produced by the core material is proportional to the current. The strength of the magnetic field increases as the current increases, resulting in an inductor that stores greater amounts of energy. This stored energy is then released once the current source is removed.

Advantages

The main advantage of these fixed inductors lies in their size and cost. Since the inductor\'s core material does not need to be replaced or reconfigured, the production cost is usually quite low. Additionally, the small size of the device allows for a high level of design flexibility. It can be used in a variety of applications, including digital circuit designs, radio-frequency circuits, and power supplies.

Conclusion

The PD43R-123M fixed inductor is a versatile device that can be used in many different applications. Its small size and low cost make it an ideal solution for a variety of electronic projects. Its simple working principle ensures that it can provide reliable performance in even the most demanding applications. With its wide range of applications and design flexibility, the PD43R-123M fixed inductor has become a popular choice for many engineers and designers.
