Fixed inductors are a type of passive electrical component that are used to directly store electrical energy in an electromagnetic field, and often take the form of a coil. The LQP02TQ4N3H02D inductor is a specialized device that is used in a wide variety of applications requiring precise control of an inductive field. In this article, we will discuss the application field and working principle of the LQP02TQ4N3H02D inductor.The LQP02TQ4N3H02D is a high quality, high reliability inductor designed specifically for SMD (Surface Mount Device) applications, such as in the automotive, industrial, communications, consumer electronics, and medical industries. It features a very high Q factor (quality factor) up to >200, which allows it to effectively store large amounts of energy in its magnetic field, making it ideal for switching power supplies, resonant circuits, voltage mode controllers, clock circuits, and more.The LQP02TQ4N3H02D has a temperature coefficient of +20ppm/°C, a rated operating temperature range of -40°C to +125°C, a rated inductance of 0.39µH(min)-1.2µH(max) at 100kHz/1V, and a rated current of 1.8A (max). It is constructed with an internal core made of Ferrite, a non-magnetic material, and with a special gapless zinc-plated steel/brass ferromagnetic outer shield on top of it. This combination of materials allows the device to have high frequency and low resistance characteristics, as well as great thermal stability.The working principle of the LQP02TQ4N3H02D is based on Faraday\'s Law of Electromagnetic Induction. When a current passes through the coil, it creates an electromagnetic field that stores energy in the magnetic field. As the current reverses direction, the energy stored in the magnetic field is released, inducing a voltage in the coil. This process can be utilized for a variety of applications, such as controlling the voltage in switching power supplies, stabilizing clock signals, and creating resonant circuits.In summary, the LQP02TQ4N3H02D is a specialized fixed inductor that is used in a wide variety of applications requiring precise control of an inductive field. Its high Q factor, wide temperature range, and special construction make it ideal for a variety of tasks such as switching power supplies, resonant circuits, voltage mode controllers, clock circuits, and more. The device works by utilizing Faraday\'s Law of Electromagnetic Induction, creating and storing energy in a magnetic field that can be released when the current reverses direction.
