Fixed Inductors

Fixed inductors are passive electronic components used to store potential energy for the purpose of providing higher current in an electrical circuit. Typical applications of fixed inductors include filtering, signal isolation, and buffering. The induction of an inductor is characterized by their inductance value, usually expressed in units of henry. Depending on their physical characteristics, inductors may also have series resistance, electrical capacitance, and dielectric losses associated with them.

LQP03TN2N9B02D application field and working principle

The LQP03TN2N9B02D is a high-density, low inductance, fixed inductor. It is specifically designed for use in DC/DC converters and other power switching circuits, where its high-frequency characteristics, low equivalent series resistance (ESR), and low voltage coefficient make it an ideal solution.

The LQP03TN2N9B02D is made up of an aluminum core with a copper wire wrapped around it, forming a single-layer coil. The electrical energy generated by the coil is transferred to the output terminals of the inductor. The inductance values of the inductors range from 1.2 to 47.5nH, making them suitable for a variety of different applications.

The working principle of the LQP03TN2N9B02D fixed inductor is based on Faraday\'s law of induction: when a changing magnetic field is present around the inductor, a voltage is induced across the windings. This voltage brings a current into or out of the inductor, impacting the current flow in the circuit. The inductance value determines how much current is passed or blocked, while the ESR and dielectric losses determine the amount of energy that is dissipated.

The LQP03TN2N9B02D fixed inductor is used in a variety of applications, such as DC/DC converters, voltage-controlled oscillators (VCOs), power factor correction circuits, and DC/AC power converters. In DC/DC converters, the fixed inductor is used to control the converter\'s output voltage. In VCOs, the inductor is used to determine the frequency of a signal. In power factor correction circuits, the inductor is used to improve the quality of the power, while in DC/AC power converters, it is used to transfer power between two different electrical systems.

In addition to these applications, fixed inductors can also be used to store energy in an alternating current (AC) system. This is done by charging the inductor with a changing current in the same direction as the current in the AC system. This stored energy can then be released back into the AC system, providing a short-term boost of power.
