Fixed Inductors: L-07W18NGV4T application field and working principle

Fixed inductors or fixed chokes are passive components which contain at least one coil of wire, often simply called an inductor, which stores energy in the form of a magnetic field. The term is widely used in electronics because in the field of electrical engineering and electronics, inductors are used to block particular frequencies. They are also used to store and absorb energy, and to help to control or shape current/voltage in both AC and DC circuits.L-07W18NGV4T is one type of fixed inductors. It is a chip amplifier with a needle inductance of 18nH and a chip power supply with a typical 5V operating voltage. The power dissipation of this chip is 0.061W and the power dissipation of the inductance is 0.0097W. It is mainly used in DSP and Class-D amplifier circuits. In terms of working principle, the inductor works on the magnetic principle, which states that when an electrical current passes through a conductor, a magnetic field is formed around the conductor. When this magnetic field is constant, the current flows in a circular path, and the flowing current produces its own magnetic field which acts in the opposite direction to the external field and causes a resistance to the flow of the electric current. This induction effect can be seen in many electronic circuits, such as transformers, regulators and amplifiers. Using this effect, the L-07W18NGV4T is able to store and release energy, and it can reduce the conduction current, providing a short-term high-current capability for a given voltage. It can also act as a frequency selector, allowing specific frequencies to pass through while blocking others. Furthermore, it can regulate or shape current/voltages in both AC and DC circuits, and it can also reduce electromagnetic interference. The L-07W18NGV4T is designed for use in both AC and DC circuits, and it is suitable for wide applications in many industries, including motor drives, audio systems, medical equipment, and telecoms. In addition, this chip has an improved power-handling capacity compared to many other standard chips due to its lower power dissipation. Overall, this chip has a wide range of useful applications, and it can be used in different types of circuits where the need for a fixed inductor is required. It is a reliable and cost-effective solution for many industrial and consumer electronics applications.
