Fixed inductors are components that maintain a specific electrical value of inductance and an AC resistance, usually used in power, audio, and RF applications. The device commonly referred to as the LQG15HH3N9C02D is a fixed inductor typically used as a power supply by-pass.

The LQG15HH3N9C02D is an inductor formed on a ceramic substrate with an air core, yielding a DC resistance value of 0.0058 ohm. It works by providing a stable AC resistance, meaning its inductance remains constant over the operating frequency range of the device. This is done through its use of a ceramic base that is able to hold a constant value of inductance. The device is shielded and has a high dielectric strength with a breakdown voltage of 25V.

In applications where the LQG15HH3N9C02D device is used as a power supply by-pass and for EMI suppression, it is placed between the power line source and the load, thus providing filtering action. This is done by attenuating the noise on the line, helping to reduce EMI and maintain necessary output voltage levels. The device also works to maintain stable current and voltage by providing an inductive path for current flow, which helps to regulate line noise and voltage changes. Additionally, the LQG15HH3N9C02D helps to improve power conversion efficiency by dissipating line noise as a result of its inductive force.

The LQG15HH3N9C02D is also used to provide a loop from one circuit node to another, which helps to reduce signal leakage and maintain circuit isolation. Its use of an internal magnetic field to store energy enables it to reduce cross-talk and circuit interference, making it suitable for applications requiring high reliability and low EMI. This type of inductor can also be used to provide impedance matching between two circuits, helping to reduce interference between signals.

Overall, the LQG15HH3N9C02D is a fixed inductor that works by providing a stable AC resistance over its operating frequency range. It is typically used as a power supply by-pass, helping to reduce the noise on the line and maintain necessary output voltage levels. It can also be used to provide a loop from one circuit node to another, to reduce signal leakage and maintain circuit isolation. Its internal magnetic field also helps to reduce cross-talk and circuit interference, making it suitable for applications requiring high reliability and low EMI.
