Fixed inductors are one of the most diverse components used in electronic device applications. Generally, conventional inductors are produced by winding a wire a certain number of times around a core. However, commercial inductors that pay attention to miniaturization tend to decrease the number of windings and core thickness, or replace the core with magnetic material. These components are commonly utilized in RF-based products such as communication equipment and cellular phones.The LGJ7045TS-471MR31-H is a fixed inductor that belongs to a series of molded chip inductors manufactured by Murata. This device has a 4.7mH inductance value and a maximum current rating of 0.43A. It also has a DC resistance of 0.034 ohms, an operating temperature range from -40°C to +125°C, and a rated voltage of 16V. This device is mainly used for low-noise and high-stability applications.The working principle of this fixed inductor is based on the concept of electromagnetic induction. When an alternating current is passed through the winding of the inductor, it induces an electromotive force in the winding, thus creating a flow of current and creating an alternating flux in the core. This alternating flux then creates a self-induced electromotive force in the inductor winding, which is opposed to the primary EMF and thus produces a decrease in current in the winding, known as an inductance.The LGJ7045TS-471MR31-H has an advantage over other fixed inductors in that it has a high self-resonant frequency and a superior thermal performance. Its robust construction makes it suitable for high-power applications. Additionally, the combination of robust construction and its miniature size results in an inductor that is both small and strong, making it an ideal choice for limited space applications.In conclusion, the LGJ7045TS-471MR31-H is a type of fixed inductor manufactured by Murata with a high inductance value and good stability. It is designed mainly for low-noise and high-stability applications, and also has the advantage of a high self-resonant frequency and superior thermal performance. Its robust construction and small size makes it suitable for both high-power and limited space applications.
