Fixed Inductors - SD7030-471-R Application Field and Working Principle

Fixed inductors are commonly used in electronic circuits, which are used for different purposes. The SD7030-471-R fixed inductor is a suitable option for this application due to its features and applications.

The SD7030-471-R is an SMD fixed inductor with an inductance value of 0.1 u Hy. It is a SMD inductor with a size of 3.2 mm length, 0.8 mm width, 0.45 mm height and has a case voltage of 50V. It has a rated current of 0.2A and provides high inductance accuracy with its inductance values. It has an operating temperature of -40°C to +85°C. The inductor has a high self-resonant frequency of 200MHz and low DCR (DC resistance) which makes it suitable for high-frequency switching applications.

The SD7030-471-R is suitable for applications such as DC-DC converters, automotive, and telecoms. It can be used in DC-DC converters to control output current and reduce power demand. It can also be used in automotive applications as it can help to store and release energy, thus reducing current loss and improving efficiency. Moreover, it can be used in telecoms for power line filtering for several applications. Furthermore, the inductor has an anti-ringing feature which helps to reduce high-frequency noise. This will help to improve circuit performance and reduce glitches.

The working principle of the SD7030-471-R fixed inductor is based on the Faraday’s law of induction. This law states that when a changing magnetic field passes through a conductor, it will induce a voltage across the conductor. The inductor is basically a coil of insulated wire. When the current passes through it, it creates a changing magnetic field. This field induces a voltage across the conductor which is proportional to the rate of change of current. This voltage opposes the current and is known as inductance. The main advantage of using the fixed inductor is that it provides high inductance with low DCR and low losses.

In conclusion, the SD7030-471-R fixed inductor is an ideal solution for applications such as DC-DC converters, automotive and telecoms. It has high inductance accuracy and a low DCR. Additionally, it has an anti-ringing feature which helps to reduce high-frequency noise. Lastly, it has a high self-resonant frequency of and operates in a wide temperature range. As a result of its features, the SD7030-471-R is an ideal choice for different types of applications.
