Fixed Inductors

Inductors are a type of electronic component with the primary function of storing energy in the form of magnetic flux. This magnetic flux is generated when current flows through the inductor. In electrical engineering, fixed inductors provide energy storage for specific types of circuits, most often power supplies or filters. One example of a fixed inductor is the RCR110DNP-390L.

RCR110DNP-390L Application Field

The RCR110DNP-390L fixed inductor is designed for use in power supply filters or general DC-DC converter applications. It has an inductance value of 390nH with an associated tolerance of ±20%. It’s a surface mount component with a 17.2 * 13.9mm package body size. This inductor features low resistance with minimal noise and high Q values, meaning it won’t interfere with the filtered circuit’s performance.

RCR110DNP-390L Working Principle

The RCR110DNP-390L fixed inductor is designed to provide stable inductive energy storage in power supply or filter circuits. The inductor works by providing a stable energy source that is capable of storing energy in the form of magnetic flux. This flux is generated when current flows through the inductor’s coil. The inductor’s ability to store energy is determined by its inductance, which is the measure of how much magnetic flux is produced when a voltage is applied across the inductor’s two terminals.

In a power supply circuit, the RCR110DNP-390L’s inductance provides the filter with the necessary energy storage to reduce any high frequency signals that may be present in the power output. This is done by the inductor’s ability to store energy, which provides an average “buffering” effect that reduces oscillations. Similarly, in a DC-DC converter application, the inductor’s inductance is designed to provide the necessary energy storage for the converter’s switching components.

Conclusion

The RCR110DNP-390L fixed inductor is an important component in power supply and filter circuits. It is designed with an inductance of 390nH, which provides the necessary energy storage for these circuits. This inductor features low resistance, high Q values, and minimal noise, meaning it won’t interfere with the performance of the filtered circuit. Therefore, the RCR110DNP-390L is a great choice for fixed inductors in power supply or filter circuits.
