Fixed Inductors

A fixed inductor is an electronic component that is specifically designed to retain its inductance in a given circuit. It is primarily used for filtering, interference suppression, tuning, energy storage, and other similar purposes. In this article, we\'ll look at the application field and working principle of the 2510R-46F Fixed Inductor.

2510R-46F Application Field

The 2510R-46F Fixed Inductor is a surface mount inductor designed for Power Over Ethernet (PoE) applications in consumer electronic devices such as mobile phones, digital cameras, remote control toys, music players, and other similar products. It is a two-terminal component with a low DC resistance that allows for efficient power conversion and current transfer. The 2510R-46F Fixed Inductor also has a high self-resonant frequency, which makes it suitable for high-frequency circuits, and is available in a range of values from 0.5 to 1.5µH.

2510R-46F Working Principle

A fixed inductor works on the basis of the magnetic field that is created when electrical current flows through it. This magnetic field induces a voltage between the two terminals of the inductor, in proportion to the rate of change of current. This property is known as inductance, and it is measured in units of henries (H). An ideal inductor has infinite inductance, but in practice, inductors are made with inductance values ranging from a few nanohenries (nH) to a few millihenries (mH).

The 2510R-46F Fixed Inductor has an inductance value of 0.5 to 1.5 microhenries. This means it has a low resistance to DC current, and a high resistance to AC current. This makes it suitable for applications such as interference suppression, as the high inductance value allows for a high impedance and a low current-limiting effect.

In addition, the 2510R-46F Fixed Inductor also has a high self-resonant frequency, which makes it suitable for use in high-frequency circuits. This is because the inductance drops to zero at the self-resonant frequency, allowing for more efficient power conversion and current transfer.

Conclusion

The 2510R-46F Fixed Inductor is a surface mount device designed for Power Over Ethernet applications in consumer electronic devices such as mobile phones, digital cameras, and remote control toys. It has a low DC resistance and a high self-resonant frequency, making it suitable for use in high-frequency circuits. This makes it a versatile device for use in various applications, such as interference suppression, energy storage, and tuning.
