Fixed Inductors

Fixed inductors, also known as inductors or coils, are electrical devices that store energy in the form of magnetic fields. They are commonly used in analog circuits to filter or tune signals. The type of inductor most commonly used in applications is the 7440620015 inductor. It has a wide range of applications, from low frequency switching power supplies to high frequency RF applications. In this article, we will discuss the application field and working principle of the 7440620015 inductor.

Applications of the 7440620015 Inductor

The 7440620015 inductor has wide-ranging applications, mainly due to its high efficiency and excellent electrical parameters like temperature and humidity. It is highly suitable for switching power supplies, DC–DC converters, medical devices, laptops and other electronic products. It also has the advantage that it does not require an inductor core.

In audio applications, the 7440620015 is especially useful when it comes to low frequency, high current loads because it can help reduce the frequency difference between input and output signals on switching power supplies. Because of this, it is commonly used to filter and tune the sound in audio amplifiers and other similar devices.

In RF applications, the 7440620015 inductor is widely used for frequency tuning and signal matching. Its high efficiency and excellent electrical parameters make it suitable for tuning RF circuits or matching components in a wide range of frequencies, from very low frequency (VLF) to very high frequency (VHF).

Working Principle of the 7440620015 Inductor

The 7440620015 inductor works based on the principle of electromagnetic induction. This means that a changing magnetic field produces an electric current in the inductor. In a switching power supply or DC-DC converter, the changing magnetic field is generated by the switching action of the power transistors.

The core of the 7440620015 is made up of stacked ferrite discs and iron wires. This gives the inductor its high efficiency and excellent electrical parameters. When the magnetic field produced by the power transistors changes, the core of the inductor responds by generating an opposing electric current.

The opposing current created by the inductor then works against the original current sourced by the power transistors, effectively reducing the overall current. This, in turn, reduces the overall power consumption of the switching power supply or DC–DC converter.

The 7440620015 inductor also has the advantage of having a very low profile, which makes it ideal for applications where size is a major factor. The fact that it does not require an inductor core also means that it is much lighter than the conventional inductors.

Conclusion

The 7440620015 inductor is a highly efficient and versatile component. It has a wide range of applications ranging from low frequency switching power supplies to high-frequency RF applications. Its high efficiency and excellent electrical parameters make it especially suitable for applications where power consumption needs to be kept low. In addition, its small profile and lack of inductor core makes it a great choice for applications where size and weight are major factors.
