Fixed Inductors: LQP03TN43NJ02D Application Field and Working PrincipleInductors, also known as coils, chokes, or reactors, are passive components used in various different electronic circuits, particularly those utilized in power system designs. These components used to store and release electrical energy, largely relying on magnetic fields and currents for the purpose. Fixed inductors are a type of inductors that have a static inductance value, and the LQP03TN43NJ02D is one of the most used inductors in the present market. This article will provide an overview of its application field and working principle. The LQP03TN43NJ02D is an inductor from Murata-EPCOs series, developed as a marking-free SMT (Surface Mount Technology) type. This inductor features a wide application, particularly in circuits for power source, clocks, mobile phones, PCs and internet communication. Most of the devices require stabilized voltages and currents, and the LQP03TN43NJ02D provides a great reliability in circuits that require power supply ripple suppression. The inductance of this component varies from 4.7 to 220 nH, allowing for easy use in various circuit designs.The most important feature of the LQP03TN43NJ02D is its working principle, which is based on Faraday\'s Law of magnetic induction. This law states that "a change in the magnetic field can induce a voltage in a conductor or a wire that is placed within the field." The working principle of the inductor is also based on the same principle. It depicts the conversion of electrical energy into stored magnetic energy and vice versa. When a current passes through the wire of the inductor, a magnetic field is generated. This field converts the current into stored energy, which is then released when the current stops.When the current applied to the inductor changes, the amount of energy stored also changes accordingly. This change is known as "inductance". So, as long as the current starts to flow, the inductor creates a magnetic field to store energy and when the current stops, the magnetic field decreases and the energy is released. This continuous process of storing and releasing energy helps maintain the stability of the power circuits.The LQP03TN43NJ02D is a highly efficient inductor that can help in minimizing the size of circuit boards, while providing the stability required for the circuit. This is due to its extremely low DC resistance, allowing for a low-energy loss. The inductor also makes use of electrodes with a high temperature coefficient of resistance, which makes it suitable for wide range of temperature-sensitive applications. In addition to that, the inductor has a built-in thermistor, which helps in preventing any damages caused due to temperature rises and surges in parasitic currents in the circuit. The parasitic current protection provided by the unit makes it suitable for voltage regulator circuits and other similar applications. Moreover, the component\'s moisture resistance is also excellent, allowing for its use in humid environments. This enables it to provide greater performance in severe environmental conditions. In conclusion, the LQP03TN43NJ02D is an inductor with a wide application in different types of electronic circuits. It is highly efficient, with extremely low DC resistance that helps in maintaining the stability of power circuits. Additionally, the component\'s built-in thermistor provides excellent protection against any temperature rises and surges in parasitic currents. These features make it a preferred component for various kinds of electronic designs.
