Fixed Inductors are electrical components used in a circuit that together forms an inductor. In a circuit, an inductance component is used to store energy in the form of a magnetic field, allowing a current to flow in a circuit without any power being used. Inductors are available in various shapes and sizes, from very small, tiny coils to extremely large coils. The B78148T1472K9 is one type of fixed inductor which has specific application field and working principle. It has a high performance and small size. It\'s designed for Pulse-Frequency circuits and PFC, SMPS, active EMI noise filter, motor drive and other power circuits. It also has a wide range of sizes and windings.The B78148T1472K9 has a Helical coil structure, which allows for a high Q value and low power loss. It also has a special coating and terminals that ensure superior performance, which leads to a reduced EMI filter loss and a high efficiency in driving motors. With a wide operating temperature range, it can tolerate higher temperatures without increasing power loss. Moreover, it has a very low DC resistance. Furthermore, it has a wide current range for different power circuits.The B78148T1472K9 has a working principle based on the Faraday\'s Law of Induction, which states that a voltage is generated when the magnetic field around a conductor is changing. The basic working principle of the B78148T1472K9 is that when an alternating current passes through the coil, the magnetic field around the conductor changes in intensity, creating a voltage across the coil. As the current increases in intensity, so does the magnetic field, and consequently the voltage across the coil increases.The working principle of the B78148T1472K9 also relies on Faraday\'s Law of Inductance, which states that an inductor, when supplied with alternating current, can store energy in the form of a magnetic field. When the current is increased, the inductor stores more energy in the form of a magnetic field, which causes a voltage to be generated across the coil. This principle is the basis for the B78148T1472K9 inductor\'s effectiveness in power and PFC circuits.The B78148T1472K9 is also known for its low resistance, which allows it to perform without causing too much heat. This is because the material used to manufacture the inductor has a low resistance in its core. As a result, the inductor is able to store more energy, improve efficiency and reliability and reduce power loss.In conclusion, the B78148T1472K9 is an efficient fixed inductor with a wide range of applications. With its high performance, small size, high Q value and low power loss, it can be used for Pulse-Frequency circuits, PFC, SMPS, active EMI noise filter, motor drive and other power circuits. Its working principle is based on Faraday\'s Law of Induction and Faraday\'s Law of Inductance, allowing it to work superbly and provide high efficiency for various power and PFC circuits.
