Fixed inductors, or fixed inductance components, are components that transfer electric energy between circuits. They are used in a variety of applications, ranging from basic signal filtering to more complex applications such as coupling. The LQB18NNR27K10D is an example of a fixed inductor, and its application field and working principle are highlighted below.

Application Field

Fixed inductors are widely used in a variety of electronic applications, from basic signal filtering to more sophisticated applications requiring coupling and other inductive functions. The LQB18NNR27K10D is designed for use in a variety of applications including power supply filtration, DC-DC converter pre-filtering, snubber circuits, phase-shift, and transformer coupling.

The LQB18NNR27K10D is designed for applications requiring high reliability and high saturation current. It is capable of withstanding power levels up to 18A, and operating frequencies up to 400kHz. It is also designed to offer an excellent RMS current capability, low DCR, and tight inductance tolerance.

The LQB18NNR27K10D is available in a range of sizes and inductance values, ranging from 0.2uH to 100uH. It is available in several package sizes and shapes, such as Toroid, Drum core, and Shielded drum core.

Working Principle

A fixed inductor works on the principle of electrical induction. Inductors are components in which electric current is passed through, and they create a magnetic field when current is passed through them. This magnetic field induces an electromotive force, which puts an opposing voltage across the component, and the resulting voltage is dependent on the inductance of the component and the rate of the current change. This opposing voltage protects against changes in current or voltage.

In a fixed inductor, this inductance value is set and does not change. This means that when a fixed voltage is applied to an inductor with a certain amount of inductance, it produces a fixed opposing voltage, and this opposing voltage remains the same regardless of how much current flows through the inductor.

The LQB18NNR27K10D is designed with a high saturation current, meaning that it can handle large changes in current without a corresponding increase in opposing voltage. This makes it suitable for use in applications such as DC-DC converters, where the current changes rapidly and the inductor needs to handle it without creating an opposing voltage that would interfere with the converter\'s operation.

The LQB18NNR27K10D also offers a low DCR, meaning that it has a low level of impedance to the flow of current. This means that it can provide an efficient transfer of power with minimal losses, making it suitable for applications such as power supply filtration.

Conclusion

The LQB18NNR27K10D is a fixed inductor designed for use in a variety of applications. It is designed to provide high reliability and high saturation current, and is available in a range of sizes and inductance values. It is suitable for applications such as power supply filtration, DC-DC converter pre-filtering, snubber circuits, phase-shift, and transformer coupling. It works on the principle of electrical induction, producing an opposing voltage to protect against changes in current or voltage.
