Fixed Inductors: The Basics of PD43R-682M Application Field and Working Principle

Introduction to Fixed Inductors

Fixed inductors are components that when energized by a current, store energy in the form of a magnetic field. The amount of energy stored is proportional to the amount of current applied to the inductor. Inductors are most commonly used in electronic circuits and are used to filter signals, and to shape frequencies to allow for better control of the signal within a circuit.Inductors come in a wide variety of sizes, shapes, and configurations depending on the application. Some typical configurations of the inductor are the fixed inductor, the air-core inductor, and the ferrite core inductor.

PD43R-682M Inductor

PD43R-682M is a fixed inductor that features a very low resistance, and a high coupling coefficient. The inductor is designed to have an optimal electrical characteristic when used in the frequency range of 0-100 MHz, with an associated range of inductance from 100 nH to 10 µH. It also features a large radial size of up to 19mm and a very low ESR of 0.01 ohm. The PD43R-682M is mainly intended for use as an inductor in DC-DC Voltage Converter applications in automotive and commercial products such as power supplies, chargers, motor controllers, and LED drivers.

How Does a Fixed Inductor Work?

A fixed inductor works according to the principle of a magnetic field being generated when a current is applied to it. The amount of energy stored in the inductor is proportional to the amount of current applied. This means that when a small current is passed through the inductor, it will store a small amount of energy, while when a large current is passed through, it will store a larger amount of energy. This stored energy can then be used to filter, shape, and control signals.The amount of energy stored is also proportional to the inductance of the inductor. The PD43R-682M has a wide range of inductance values, with a range of 0.1 nH to 10 µH. The higher the inductance, the more energy is stored, and the more effective it is at filtering signals.

Conclusion

The PD43R-682M fixed inductor is a highly efficient component for inductive applications. Its low ESR and wide frequency range make it an ideal choice for DC-DC voltage converter applications. The amount of energy stored is proportional to the amount of current applied and the inductance, allowing for precise control of the signal in the circuit.
